Dear Sirs.
About "Thran Vigil" it activates twice their effect when a creature leaves the graveyard.
I wanted to informed you so that you can solve it.
Warlords Elite mentioned that "as an additional cost to cast this spell, tap two untapped artifacts, creatures, and/or lands you control". I was playing and I could target two tapped lands in order to play "Warlords Elite". I wanted to notify this bug to MTGO staff so they can fix it.
