A Simic Trinket Kitty deck. Goal is to value your way to wins by bouncing Coiling Oracle for extra cards as well as using the Trinket Mage toolbox to good effect.
Dream Stalker is used occasionally to bounce itself (to grow Cloudfin Raptor) but most often to bounce Coiling Oracle, Skyshroud Ridgeback, Trinket Mage,
Reality Acid
or Wickerbough Elder if you need to deal with multiple enchantments.
T1: Ridgeback or Raptor
T2: Coiling Oracle
T3: Dreamstalker and bounce Oracle, or Trinket Mage for Bonesplitter
T4: Replay Oracle, play Bonesplitter, play another Ridgeback
T5: Buff your creatures with Rancor or Bonesplitter, or fetch Explorer's Scope if it looks like the game might go long.
T6:
Stitched Drake
might work here if a Ridgeback has timed itself into the graveyard.
T7: You should be swinging for a pile of damage here. Protect your creatures with Vines and counters from this point out.
