Introducing Rainbow Mewtwo — The OCIC Secret Deck!

Hello! I’m very excited to present to you a new archetype I call “Rainbow Mewtwo”. It’s a deck I worked on for a long time in preparation for the Oceania International Championships and I almost played it, although I changed my mind in the end. If you’ve seen the crazy Mewtwo and Mew-GX deck that Henry Brand played at the event, then you have an idea of what you’re in for today.

The Sword & Shield set brought Aurora Energy to the format, a strong card for Mewtwo and Mew-GX since it can power up any attack and discard an attacker at the same time. It’s no surprise the card is played in most Mewtwo and Mew-GX / Malamar and Welder lists. You would expect it to replace Rainbow Energy completely, but it’s possible to play four copies of both Rainbow Energy and Aurora Energy to give the deck eight multi-type Energy cards.

Why does this matter? Instead of having to limit yourself to (mostly) one type like the two main Mewtwo and Mew-GX variants (Welder and Malamar), you can use any attacker you want regardless of typing. One of the attacks you can use is Solgaleo-GX‘s Sol Burst GX, a card that’s been in the format since early 2017! It has seen very little play so far since Metal wasn’t a very attractive type. However, thanks to Rainbow Energy and Aurora Energy, you can have eight multi-type Energy that gives good odds of pulling off a turn one Sol Burst GX. Welder is supposed to be the fastest Energy acceleration in the format, but Sol Burst GX is more explosive, since you can end your turn 1 with six Energy cards in play! This gives you an incredible amount of options for your second turn as you can copy attacks of any Pokemon-GX, from Reshiram and Charizard-GX to Flygon-GX. You can benefit from any card that favors a specific type of Energy such as Zeraora-GX‘s Thunderclap Zone too. The freedom you have in building the deck and in playing it is unprecedented.

Have I caught your attention yet? If so, let’s explore this concept in detail. I’ll start by explaining briefly how the idea came to be and how the deck works. Obviously, the deck has many moving parts, but there is a unique core that I’ll discuss. As much as I wish I had a perfect list to feature, I spent a lot of time moving cards around and never settled on one exact decklist. This article features the latest list I played, as well as some options for the deck.

Finally, I’ll focus on the deck in the context of the metagame: How to play the most expected matchups and why I ultimately chose not to play Rainbow Mewtwo. The deck does have some issues I’m struggling with to this day. But I’ll explain some ideas that could help to solve these issues.
