Whenever a player casts their second spell each turn, that player and target opponent each discard a card.
Whenever a player discards a card this way, put a discussion counter on Godwin's Law.
When Godwin's Law has five or more discussion counters, sacrifice it. Each player discards their hand, then draws four cards.
"As an online discussion grows longer, the probability of invoking historical comparisons approaches 1."
