Flying, trample
When Tanazir Quandrix enters, double the number of +1/+1 counters on target creature you control.
Whenever Tanazir Quandrix attacks, you may have the base power and toughness of other creatures you control become equal to Tanazir Quandrix's power and toughness until end of turn.
Build a wide board of creatures and stack +1/+1 counters, then deploy Tanazir to double them on a key threat. Attack to copy Tanazir's huge power/toughness onto your whole team for a one-shot alpha strike, ideally with trample or evasion. The deck plays as a Simic counters midrange/go-wide hybrid that snowballs from incremental growth into a lethal swing.
Add more counter doublers (Hardened Scales, Branching Evolution, Doubling Season) and proliferate engines to make the doubling trigger lethal faster. Improve evasion and protection—Heroic Intervention, Snakeskin Veil, and trample-granters like Rancor or Inkmoth—so your one-big-swing doesn't get blown out. Tighten the curve with efficient ramp (Sol Ring, Birds of Paradise) and a dedicated overrun finisher to convert board states the same turn.
