first edition mewtwo card 1999 Pokémon Mewtwo Base Set Unlimited Holo #10 PSA 8 NM-MT – Domino City Gaming [PP] Barrier Mewtwo :1ED : Old Back

Run up to 1, though many players won't really bother

A lot of Tricky Terrain is designed to suck lands out of the deck and get them onto the playing field

Although I would imagine they would have to dramatically increase the number of usable cards if they planned to do that

If you can pull off the time counters to circumvent its suspend 6 then it's great

More than 5 years have passed since its first appearance, it has "double piercing damage", and there is also the existence of "Blue-Eyes Chaos Dragon" that can be ritual summoned under the same conditions, so it will be a difficult development if you can survive with only 2 monsters
