Just lost a fight because opponent got a new Silverstrike support EVERY turn. Is that possible? Can’t read supports because of current bug, so I have no way of telling what could be causing that. Opponent was playing Gideon.
Maybe your opponent had Starfield of Nyx on the board?

He probably had a Starfield of Nyx on the board. I use that with Silverstrike and insidious will to control the board.
Combine that with Sigil and yikes… Hope I draw it in a pack before I die. 
Thanks for response. That is broken as can be! Like NPE-levels of OP.
