count(enemies having TAG)lettemplate archetype

A guard the other side must attack first, lifted from the card slice's content\guard.ledger (Guarding) and the board's attack from content\rules.ledger (Ready, Attack, Mortal and the Body template). A unit attacks once a turn, from the turn after it is played, each of the two dealing its attack to the other at once; while the other side has a guard, only a guard may be attacked. A spell isn't held by it. The guard's tag is held by an effect, not the card, so the hero keeping the card in its hand is no guard; here the units stand on the board.
