Time Zone Conversions for Battle Window
The battle phase runs from Thursday, August 20 at 23:00 through Sunday, August 23 at 22:59 in America/Fortaleza time zone (BRT, UTC-3). Players in other regions should convert the UTC times above to their local zone to avoid missing the window.
Format and Rules: Regulation M-B Singles
MCS August 2026 uses Singles format under Regulation Set M-B, the same ruleset governing the current ranked ladder through Season M-5 (which ends September 9, 2026 at 01:59 UTC).
What Regulation M-B means:
Regulation M-B is the second major format for Pokemon Champions. It replaced Regulation M-A on June 17, 2026 alongside the mobile version launch. The full Pokemon eligibility list and restricted/banned Pokemon are documented in the official announcement at https://news.pokemon-home.com/en/page/776.html.
Key format points for team building:
- Singles, not Doubles: Bring 6, battle with 1 at a time in turn-based Singles. This is not VGC Doubles format.
- Regulation M-B pool: Check the official page above to confirm your Pokemon are eligible. Not all Pokemon from prior formats are legal in M-B.
- One Mega Evolution per battle: You can bring multiple Mega-capable Pokemon, but only one can Mega Evolve per match.
- No duplicate items: You cannot use the same held item on multiple Pokemon in your team of 6.
If you have been climbing the ranked ladder in Season M-5, the team you are using there is already legal for MCS August — no adjustments needed unless you are experimenting specifically for the competition.
For team building help, see our team builder guide and best teams for ranked. The Regulation M-A tier list is labeled historical — it does not reflect the current M-B meta, so treat it as reference only.
How to Enter MCS August 2026
Entering the competition is straightforward if you follow the steps below. You have until Monday, August 24 at 01:59 UTC to register.
Step-by-step entry process:
- Open Pokemon Champions on your Switch or mobile device (iOS/Android).
- Go to Battle → Online Competitions from the main menu.
- Select the Monthly Challenge Series August 2026 event from the list.
- Register a team of 6 Pokemon that meet Regulation M-B requirements. The game will block you from registering an invalid team.
- Confirm your registration. Your team is now locked for the battle phase unless you withdraw before August 21 at 02:00 UTC.
Can you change your team after registering?
Yes — but only before battles start. If you withdraw from the competition before the battle window opens on August 21, you can re-register with a different team. Once the battle phase begins, your team is locked permanently for the event. You cannot withdraw and re-enter after battles start.
Do you need a specific rank to enter?
No. The competition is open to all players regardless of where you stand on the ranked ladder. New players who just finished the tutorial can enter on equal footing with Champion-tier veterans.
Rewards: Alolan Raichu, Quick Coupons, and Titles
MCS August 2026 offers two tiers of rewards: participation rewards for everyone who completes the minimum number of battles, and placement titles for top finishers.
Participation Rewards (3+ Decided Matches)
Complete at least 3 decided matches during the battle window (August 21–24) and you receive:
- Alolan Raichu (the original Alolan form — Electric/Psychic-type, Surge Surfer ability)
- 100 Quick Coupons (in-game currency)
- Title: “MCS 08/2026 Challenger”
What is a “decided match”?
A decided match is any battle where one player wins and one player loses. Forfeits, disconnects that result in a loss, and battles that time out all count as decided. What does NOT count: battles where both players disconnect simultaneously, or battles where a network error prevents a winner from being recorded.
Is the Alolan Raichu reward exclusive to this event?
The official announcement does not specify whether this Alolan Raichu is exclusive or can be obtained elsewhere. Alolan Raichu is distinct from Mega Raichu X and Mega Raichu Y (which were free login rewards for players who logged in before September 2, 2026, distributed via the in-game mailbox). See the mega evolution guide for details on Mega Raichu forms.
Placement Titles (Top 10,000)
Finish in the top 10,000 players worldwide and you earn an additional title based on your exact placement:
| Placement | Title Earned |
|---|---|
| Ranks 1–10 | MCS 08/2026 Master |
| Ranks 11–100 | MCS 08/2026 Veteran |
| Ranks 101–1,000 | MCS 08/2026 Ace |
| Ranks 1,001–10,000 | MCS 08/2026 Rising Star |
Placement titles are in addition to the Challenger title — a player who finishes rank 50 receives both “MCS 08/2026 Challenger” and “MCS 08/2026 Veteran” titles.
How competitive is top 10,000?
The competition is open to all players globally, and Pokemon Champions has a large player base following the June 2026 mobile launch. Reaching top 10,000 requires strong performance but is realistic for semi-competitive players who complete a high volume of battles with a tested team. Reaching top 100 or top 10 requires significantly higher skill and consistency.
Battle Strategy: What to Expect in Singles M-B
MCS August 2026 runs on the same ruleset as the current ranked ladder — Singles format under Regulation M-B. This means the eligible Pokemon pool, banned Pokemon, and battle rules are identical to what you face in Season M-5.
What team archetypes perform well in Singles M-B?
As of mid-August 2026, the ranked ladder data for Season M-5 (Regulation M-B) is still accumulating. The tier list on this site reflects Regulation M-A (the prior format, which ended June 17) and is labeled historical — it is not an accurate representation of the current M-B meta.
If you are building a team specifically for MCS August, your best resources are:
- The current ranked ladder: play 10-15 matches in Season M-5 to see what opponents are running most frequently.
- Community databases like Pikalytics (if M-B data has been published for Doubles/Singles).
- The official ruleset page at https://news.pokemon-home.com/en/page/776.html to confirm which Pokemon are newly eligible or restricted in M-B compared to M-A.
For general teambuilding principles that apply across formats, see the team builder guide, cores guide, and switching and prediction guide.
Quick Coupons: What They Do
The participation reward includes 100 Quick Coupons. Quick Coupons are an in-game currency used in the Pokemon Champions shop. The official announcement does not specify what Quick Coupons can purchase — check the in-game shop for the current inventory.
Relationship to Season M-5 and Regulation M-B
MCS August 2026 runs during Season M-5, the current ranked season that started August 5, 2026 and ends September 9, 2026 at 01:59 UTC. Both the ranked ladder and the MCS competition use the same Regulation M-B ruleset, which has been active since June 17, 2026.
Regulation M-B official page: https://news.pokemon-home.com/en/page/776.html
Season M-5 announcement: https://champions-news.pokemon-home.com/en/page/803.html
Regulation M-B was originally scheduled to end September 2, 2026, but the official page confirms it has been extended through September 9, 2026 at 01:59 UTC. This means the MCS August competition and Season M-5 both operate under M-B rules, and any team you build for one is legal in the other.
