First strike (This creature deals combat damage before creatures without first strike.)
Reach (This creature can block creatures with flying.)
At the beginning of combat on your turn, put X +1/+1 counters on another target creature you control, where X is Halana and Alena’s power. That creature gains haste until end of turn.
If Halana and Alena's power is somehow negative at the time its triggered ability resolves, you will put no counters on that creature. The effect doesn't remove counters from that creature or give it -1/-1 counters.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
