Whenever Talus Paladin or another Ally you control enters, you may have Allies you control gain lifelink until end of turn, and you may put a +1/+1 counter on Talus Paladin.
"Why fill pockets with gold when you can fill hearts with conviction?"
The choices you make as Talus Paladin’s ability resolves are made individually. First you decide whether to have Allies you control gain lifelink until end of turn. Then, regardless of that decision, you decide whether to put a +1/+1 counter on Talus Paladin.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
