Nine Extremes Invasion

Nine Extremes Invasion is a variation of Heaven's Gate Blockers with focus on 9 cost blockers, specifically mouse-themed Invaders. Due to its heavyweight cards, this deck has seen little to no competitive use, but if one manages to pull off at least one Invasion, they might be able to turn the tides in their favor.

How to use
While Kijitron, Four Extremes is the best way to start the game, it is rather slow and thus hand replenishment and mana acceleration beforehand are preferable. If the opponent uses a beatdown deck, the player can respond with Shivainu, Two Extremes's Strike Back or Heaven's Gate's shield trigger.

Once you have the desired cost 9 creatures out, attack and use Invasion to evolve them into stronger finishers like Chutopia, Super Nine Extremes or Momotarus, Super Nine Extremes. Next turn, attack with the evolution creature and evolve it into G.O.D., Extreme Invasion, then spam your entire battle zone with cost 9 creatures which will seal your victory. Although G.O.D.'s Invasion requirements are somewhat harsh, if pulled out they will be very rewarding.

Weaknesses
At its basis it is a gimmick deck and as such it falls victim to many anti-meta strategies, especially those of stronger controls. Since it is a Heaven's Gate Blockers deck, it is an easy prey for discards. Furthermore, Oriotis, Control Wings can put a stop to cost trampling cost 9 blockers, so additional early removal would be preferred.

Trivia
DMD-28 Custom Transformation Deck Revolution vs. Invasion: Dragonic Polaris Light Civilization core and Invader sets contain enough parts to build this deck, but cards such as G.O.D. and Chutopia would still have to be bought separately.
