Highlander because you arent allowed to have more than one of any card in your deck (other than basic land)
Ikoria: Liar of Behemoths doesnt seem to have any immediate standouts along the lines of Uro, Oko, or Once Upon a Time (thankfully), but there is still a deep roster of playables that will make an impact
The mechanic was introduced in 1996s Mirage block, which told the story of the planeswalker Teferi Akosa and how his experiments with time manipulation affected the continent of Jamuura
The deck then adds powerful midgame threats with strong abilities including Basri's Lieutenant (+1/+1 counters and creature tokens), Basri's Acolyte (lifelink, +1/+1 counters), Valorous Steed (creature tokens), and Falconer Adept (creature tokens)
You see, Emiel also has an ability that allows you to pay one White or Green mana to put a +1/+1 counter on your Creatures that enter the battlefield
