If you return a Character to a player's hand, the following happens:
- Tokens can be redeployed for 0 cost
- Abilities targeting the Character still resolve
- The Character retains stats changes while in the hand
I was playing against the Genesis AI and used Stumble to bounce a Genesis Construct (4/4) while I had initiative. I followed up with a Heat Wave to wipe several Unending drones. There was a Bad-Bot in play and I figured the AI would sac it to pump the Genesis Construct. I was exactly right and as far as I could tell, it went straight to the graveyard. The next turn, a 14/13 Genesis Construct entered play. This means that Aleta pumped it (+1/+1) and the Constructor was able to successfully sac the Bad-Bot (then a 8/7) to give it +9/+8.
Part of purpose for bouncing creatures in MTG is to reset creatures with attachments or kill creature tokens, but IW seems to preserve them. Is this intentional or a bug?
