The first drops for two, gives you an 0/5 Wall, and you can put -0/-1 counters on it to make mana
Genesect-EX 64/124 - Fates Collide Holofoil Genesect-EX 64/124 - Fates Collide Holofoil The Pokmon Company Once during your turn (before your attack), you may put a Pokmon Tool card attached to this Pokmon into your hand
I like that Szarekh, the Silent King is a card advantage engine that passively enables your graveyard synergies, but the deck isnt light on self-mill and has a much better option for the command zone
(As an aside to that, do you have the discipline to dump the fun card to make sure you keep the Mana Rock?) If so, perhaps fewer (ramp spells, not Lands) are warranted
All of this results in a deck with no synergy on paper, but in-game, a beautiful - if chaotic - well-oiled machine with one goal: get Exodia
