Why pass up an opportunity to print my cards with someone else's ink
Ghalta, Primal Hunger Ive seen this creature be cast as early as turn 3 or 4, and I can imagine some play patterns allow you to cast it even sooner
The idea behind Level 0 could be interesting, but then it would break any Synchro with a multiple monster requirement for it's non-Tuners (Mist Worm etc.) but would be neat
Light-Paws, Emperor's Voice A good aura Light-Paws, Emperor's Voice is a two-mana White 2/2 that reads: "Whenever an Aura enters the battlefield under your control, if you cast it, you may search your library for an Aura card with mana value less than or equal to that Aura and with a different name than each Aura you control, put that card onto the battlefield attached to Light-Paws, Emperors Voice, then shuffle." This is undoubtedly going to be an almighty card in Commander but, given how potent the ability is, we wouldnt be surprised to see this at the forefront of an aggressive aura deck in other popular MTG formats too
