In that form, it has the single highest base stat total of any Pokemon at 1125, which is insane
Why not just Solitude/Ephemerate and get a five-mana creature for one-mana, and take two of your opponents creatures along with it
Aquitects Will, Phantasmal Terrain, Dream Thrush, Grixis Illusionist, Opposition, Parallax Tide, Reef Shaman, Seas Claim, and Spreading Seas are among the cards that can either change an opponents land into a useless land type, or just get rid of lands for an extended period of time
Some monsters (such as "Elemental HERO Rampart Blaster" and the "Superheavy Samurai" monsters) may attack in face-up Defense Position
So: Are these are worth it
