Double strike (This creature deals both first-strike and regular combat damage.)
When Drizzt Do'Urden enters the battlefield, create Guenhwyvar, a legendary 4/1 green Cat creature token with
trample (This creature can deal excess combat damage to the player or planeswalker it's attacking.).
Whenever a creature dies, if it had power greater than Drizzt's power, put a number of +1/+1 counters on Drizzt equal to the difference.
