If a source would deal 4 or more damage to a permanent or player, that source deals 3 damage to that permanent or player instead.

Exile all artifacts and creatures with mana value 3 or less. They perpetually gain "This spell costs more to cast" and "This permanent enters tapped."
For as long as each of them remain exiled, its owner may play it.

Each player chooses a creature they control. Destroy the rest.
