Siren's Call - Fourth Edition (Uncommon)

Siren's Call is an instant from Fourth Edition that forces your opponent's creatures to attack during their turn. This can disrupt their strategy and leave them vulnerable, as any non-Wall creatures that don't attack get destroyed at the end of the turn. It's particularly effective in decks that leverage combat tricks or want to exploit aggressive strategies, but timing is crucial since it must be cast before attackers are declared.
