Take Up the Mantle (Yellow)

Whether the targeted attack action card is attacking a marked hero this turn is checked when Take Up the Mantle resolves on the stack.

If the target is attacking a marked hero, the target will get +3 (not optional). The effect that banishes a card is optional and if you do, the target becomes a copy of the banished card.

If the target is attacking a non-hero, or the defending hero only becomes marked after Take Up the Mantle has already resolved on the stack, the continuous effect will remain at +2 and you do not banish a card.

When the target becomes the chosen card, ALL of its properties are replaced by a copy of what is printed on the chosen card. This includes name, cost, color, power, defense (if any) etc. Then, when this leaves the arena, it reverts back to its own properties.

When the attack becomes the chosen card, any layer-continuous effects that were applied to the attack will continue to apply after it becomes a different card.E.g. If Razor Reflex (red) was played on the attack, both the +3 and triggered ability would still apply after Take Up the Mantle, even if the new cost of the attack is 2 or more. Notably, the +3 given to the targeted attack action by Take Up the Mantle will continue applying after it has become a copy chosen card.

When the attack becomes the chosen card, new layer-continuous effects may begin to apply to the attack when it becomes the chosen card, except for “next attack” effects which only apply if the attack met the condition when it was played/activated/triggered (e.g. Prismatic Leyline).

When the attack becomes the chosen card, any static-continuous effects that were applied to the attack are re-evaluated whether they’ll continue to apply.
