Further Upgrades The first cards I'd pick up to further juice up the deck would be untapped mana-fixing lands: Watery Grave, Shipwreck Marsh, Underground River, Morphic Pool, Darkslick Shores, Polluted Delta, Sunken Ruins, Undercity Sewers, Urborg, Tomb of Yawgmoth and then maybe a couple more Island / Swamp fetches
This is the POKEMON CENTER EXCLUSIVE ETB
Combined with Mega Absols cult-favourite status, the card stands out as a naturally coveted pull
Valgavoth even comes with built-in evasion and protection thanks to the flying and ward keywords
