Mewtwo ex and Hypno deck This deck is back to pure Psychic typing, as now Mewtwo ex has freedom to be in either the active slot or bench slot while Hypno suppresses the enemy with sleeping effects
The rest of the Spell Cards are meant to support the Gate Guardian pieces--usually to get the pieces out on the field as quickly as possible
The trade-off is that your opponent gains life equal to that creature's power, but that doesnt matter much in a game
This, for example, means that (most) Water types are weak to Lightning but not Grass, while Fire types are weak to Water but not Ground (which has been combined with Fighting)
Considering the sales, execs probably saw it as a good decision
