A more dedicated "Jurrac" Deck can use the archetype's Field Spell, "Jurrac Volcano", which can destroy a Dinosaur to search a "Jurrac" monster, protects "Jurracs" from destruction, and has another effect to Summon "Jurrac Meteor"
If that's the case, you should do a bit more research and find out more about the game before you design cards
I also appreciate that it stores away cards that are discarded for any reason, perhaps from cycling, or an opponents hand disruption effect
But it isnt as great on its own
I either use it for ramp with Rapacious Dragon or even Goldspan Dragon Or it could be a token generator with Siege-Gang Commander or Myr Battlesphere mixed with Impact Tremors does a LOT of damage
If it already had a +1/+1 counter, it will stay dead in the graveyard
