Midweek Magic: Slow Start - I don't recall for sure who was first player

My Dazzling Angel equipped with Basilisk Collar blocked my opponent's +1/+1 Forest from Earthbend 1 from Badgermole Cub. Both died. (This action sent my creature to my graveyard and returned the Forest to the battlefield under my opponent's control and set off a chain reaction of +1/+1 buffs for my opponent's creatures, at which point I captured the log, then conceded, then captured the screenshot.)

What I expected:
1. My 2/3 Dazzling Angel deals 2 Deathtouch combat damage to 1/1 Forest.
2. Opp's 1/1 Forest deals 1 combat damage to my 2/3 Dazzling Angel.
3. I gain 2 life due to Lifelink.
4. Opp's 1/1 Forest dies and gets returned to the battlefield (setting off a chain reaction of buffs).
5. My 2/3 Dazzling Angel remains on the battlefield, healing its 1 damage at the end of opp's turn.

I see no modifiers on the battlefield that should affect this combat damage interaction otherwise.

Probably unrelated, but note that the log mentions the Command Zone a couple times. I'm unaware of any cards in this duel that should touch that zone.
