My turn, declare blockers step, attacking with a Tajuru Stalwart (3 +1/+1 counters via converge) opponent declares Drana's Emissary to block the Stalwart. I pass priority, he casts Unnatural Endurance. It resolves. On the empty stack, I cast and resolve Gift of Tusks targeting Emissary. No other effects for combat. Can you state the condition of the Emissary and walk through the rest of the combat until the 2nd main phase?
Drana’s emissary will be 5/3. (Base P/T of 3/3 from Gift of Tusks and +2/+0 from Unnatural Endurance)
During the combat damage step, Tajuru Stalwart will assign 3 damage to Drana’s Emissary and Emissary will assign 5 damage to Stalwart. The damage will then be dealt.
When state-based actions are checked, both creatures would be destroyed because of lethal damage, but Drana’s Emissary has a regeneration shield on it from Unnatural Aggression, so it regenerates instead of being destroyed.
When the second main phase begins, Tajuru Stalwart is in your graveyard and Drana’s Emissary is tapped on the battlefield with no damage marked on it.
