While playing a rogue deck, I discovered and played the Priest quickdraw card ‘Benevolent Banker’, to discover a spell from my opponent’s deck. I chose my opponent’s Protoss spell ‘Chrono Boost’.
When I cast the stolen Chrono Boost, it did nothing. Although I had no Protoss cards to draw, I was still expecting it to summon a 3/4 Zealot.
