2 Non-foil borderless or extended-art rare of mythic rare cards This can be one of the 43 borderless rares (46.2%) or 17 mythic rares (9.2%, including 5 borderless planeswalkers)
Even Exiled Creatures do not get rid of Rancor as the Enchantment itself doesnt get Exiled
When this enchantment leaves the battlefield, each player shuffles their hand and graveyard into their library
On paper, that is a good strategy because his field spell, Ancient City - Rainbow Ruins, gains increasingly powerful effects for each one, and if the backrow is full can summon a monster from there each turn, and if it happens to be Ruby Carbuncle it will result in a massive advantage
Since each belongs to 2 of the original Onomat archetypes (or all 4 in the case of Utopic Onomat), their effects synergize really well with each other, meaning if you have 2+ unique Onomat Monsters, all of them can be Summoned to the field on that turn.
