pokemon card marshadow gx - SM59 [Fighting] Peerless Hundred Blows GX GX 50 This attack does 50 damage times the amount of basic Energy attached to this Pokemon Pokémon Marshadow-GX - 156/147 -

The Unknown cards were pretty gimmicky, but this one was by far one of the most useful ones

The Phyrexian Debaser was a flying 2/2 carrier that could be sacrificed to give target creature -2/-2 until end of turn, the Phyrexian Defiler a 3/3, that could be sacrificed to give target creature -3/-3 until end of turn and all of this was somewhat useful, but not as fear inducing as Phyrexian Plaguelord, the one carrier to rule them all

To me, both cards look to be in great condition

Attack 2: [3] Metronome Choose 1 of the Defending Pokmon's attacks

We have tons of variants on this over the years, but check out the everyone Exploration of Rites of Flourishing or the planeswalker of Jace Beleren that no one wants to kill or Font of Mythos for two cards
