Sorry for not capturing a log, I wanted to finish the game out of courtesy to my opponent.

I was playing a modified Villains of Darkness deck from the Final Fantasy starter kit. I had added some cards, including Tinybones, The Pickpocket and Imposter Syndrome. My opponent had indestructible and hexproof creatures out, including a Herald of Eternal Dawn, and had earlier played 4 Momentum Breakers and sacrificed them so they were in the graveyard. I had, among others, Tinybones, the Pickpocket out, along with two token copies of him from Imposter Syndrome. I hit my opponent with all three Tinybones, and grabbed three different Momentum Breakers from his graveyard with Tinybones' ability. At the end of the turn, I was only given the opportunity to play one of the Momentum Breakers, rather than all three, which would have forced my opponent to sacrifice the hexproof creatures, as I wouldn't be targeting the creatures.

Steps to replicate.
1. Have out Tinybones, and at least one copy of him.
2. Opponent has 2 Momentum Breakers in their graveyard.
3. During combat, have all the Tinybones deal combat damage to the opponent
4. Select different Momentum Breakers from opponent's graveyard with the Tinybones' abilities.
5. Attempt to play the Momentum Breakers using Tinybones' abilities.
