Strategy is to move counters from small creatures onto cool creatures with trample or unblockable. It's an aggressive stompy approach that uses counters instead of, or in addition to, pump spells. Advantage is that you can keep moving the counters to your best creature, with the possibility of using Bioshift to move counters off a creature that is about to be destroyed. Bioshift works well with
Setessan Oathsworn
as it gives the +2 buff in addition to the counters you are moving. Get a counter onto Oathsworn ASAP and then cast Mutant's Prey to punch out your opponent's fatty (extra counters will resolve before the spell does).
Play Beaqueathal on your own creatures with graft or your blockers (tokens, beetles) to get more cards.
A great start to the game would be:
T1: Land, Simic Initiate
T2: Land, Pit-Skulk or Ledgewalker. Don't sac the Initiate yet. Play Bequeathal on the Initiate if you can.
T3: Play a third creature and sac the Initiate or buff a creature with a counter from a Beetle.
T4: Play Oathsworn here, but expect it to die unless you have protection (Vines).
T5: Buff Oathsworn with Vines, Rancor or Bioshift and swing for the kill.
