5. Cast Arcbond by paying 2, targeting Zada.

7. Resolve each Arcbond, causing each creature you control to deal damage to each other creature and player when they are dealt damage.
8. Deal damage to any creature you control, triggering their Arcbond ability, dealing that much damage to each other creature and player.
9. The creature's lifelink triggers, causing you to gain life equal to the damage dealt.
