Blocking creatures gain first strike until end of turn.

: Choose target attacking or blocking creature whose controller controls an Island. Dwarven Sea Clan deals 2 damage to that creature at end of combat. Activate only before the end of combat step.

Bird creatures get +1/+1.

: Target Bird creature gains banding until end of turn. (Any creatures with banding, and up to one without, can attack in a band. Bands are blocked as a group. If any creatures with banding a player controls are blocking or being blocked by a creature, that player divides that creature's combat damage, not its controller, among any of the creatures it's being blocked by or is blocking.)
