Time Walk is one of the most powerful cards in "Magic: The Gathering" because it gives you an additional turn. Sage of Hours is a new blue mythic rare creature card spoiled from Wizards of the Coast's upcoming expert expansion set "Journey Into Nyx" that can potentially give you unlimited turns. You don't need infinite turns for Sage of Hours to win you the game though: Just one extra turn can potentially do the trick.
Sage of Hours - 1U
Creature - Human Wizard (Mythic Rare)
Heroic - Whenever you cast a spell that targets Sage of Hours, put a +1/+1 counter on it.
Remove all +1/+1 counters from Sage of Hours: For each five counters removed this way, take an extra turn after this one.
In Standard there's a lot of cards that deal with +1/+1 counters. Give will put four +1/+1 counters (three from the card, and one from the Heroic trigger) on Sage of hours for just three mana. Bioshift and Simic Fluxmage move around +1/+1 counters between your creatures. Kalonian Hydra will double the amount of +1/+1 counters on all your creatures every time it attacks. When Vastwood Hydra dies, you can put all it's counters on Sage of Hours. Going Bant allows you to splash in Ajani, Mentor of Heroes and gain three additional counters each turn. Primeval Bounty can help you rack up counters too.
In eternal formats gaining infinite turns with Sage of Hours isn't that hard, especially if you don't mind clunky combos that require several cards and are by no means competitive. This player loves using obscure older cards. Once Sage of Hours has a counter on it, you'll be able to cast Clockspinning with buyback for 1U (provided you control a Memory Crystal) to put two additional counters on it. Doubling Season (okay, perhaps not so obscure) will double the amount of counters every time, and Evolution Vat can help you too.
Sage of Hours might not be the flashiest mythic rare (it's not a god, planeswalker, or busted card), however that means you'll be able to pick up a play set fairly cheaply and have a blast with it.
