Conjuro
Elige hasta dos criaturas objetivo y pon un contador +1/+1 sobre cada una. Puedes buscar en tu biblioteca y/o cementerio una carta llamada Basri, paladín devoto, mostrarla y ponerla en tu mano. Si buscas en tu biblioteca de esta manera, barájala.
You can cast Basri's Aegis without any target creatures. You'll just search for Basri, Devoted Paladin.
If do you choose targets and each target creature is an illegal target by the time Basri's Aegis tries to resolve, the spell won't resolve. You won't search for Basri. If just one target is still legal, however, you do put a +1/+1 counter on it and search for Basri.
