I had four Mirari's Wake cards in play and tried to use Heliod's Intervention for life gain with 40 mana. The game immediately resulted in a draw. It gave the warning, after the fact, that I needed to take another action as if I had done the same thing multiple times, but this was the only use of the card. This has happened before and is not a one off.

Expected reult - gain 80 life.
Actual result - Game ended in a draw.
