dinosaur deck mtg commander Gishath, Sun's Avatar Tribal Magic lost ruins Dinosaur Commander Deck - Custom

This card costs X and three green, has Convoke - meaning you can tap creatures to help you pay for the cost - and you can search your library for a creature that costs X or less and put it into play at instant speed

Like a lot of the other cool, iconic legends in the set, 6 mana is a lot, but being able to flip this guy into a 9/9 that fights a creature, gives you a ton of mana, and eventually turns back into Clive rather than dying, could make it all worth it

Then theres the last mode, which can create an Eldrazi Scion token creature to act as a chump blocker or provide some Treasure-like mana acceleration

Obviously we can go further with this, running a dedicated Lands deck that looks to fill our graveyard with lands and other stuff via cards like Faithless Looting and Life from the Loam, recur our stuff with Windgrace and stuff like Splendid Reclamation, and throw in cards that care about lands (Avenger of Zendikar)
