A 5/5 with vigilance and lifelink, he can ETB to swap life totals with an opponent and if you lose life in the process, you draw that many cards
For myself, I kind of a wayside fan at this point, where I play one of the games every now and then and follow news, but I'm not as hyped at every announcement
I can say that its a very well received format, with plenty of complexity, overlap and synergies
With mass blink effects, his second ability is basically a mass blink spell for three mana, and you can use the Blood to rummage away cards you dont need or fill your graveyard to blink things
Any Mouse Soldier or Otter Wizard is sure to be endearing
I might be biased, but I think this card is pretty strong and will do more work than youd expect especially in cEDH with access to cheap or free legendary creatures
