Untap Stuff for V A L U E feat. Willbreaker (Modern) [Revision 25]

This deck just plays a bunch of creatures that can tap for something like mana or card advantage and stuff that can untap those cards for V A L U E.
While generating tons of card advantage with Arcanis the Omnipotent and Experiment Kraj that copies its ability, we can also untap our mana dorks for even faster mana acceleration as our heavy hitters are all five mana or more. Sigiled Starfish is also pretty nice with top-deck-manipulation, especially in the early game when we want to hit our good stuff as soon as possible. In the late game pure card advantage will be provided by Arcanis the Omnipotent.

Our win conditions are Willbreaker and Experiment Kraj, as we can also untap the creatures of our opponent to steal them with Willbreaker, and Experiment Kraj will just grow itself and other creatures pretty big if left on board unanswered and it also can help with the Willbreaker gameplan.

To untap our creatures we play Kiora's Follower and, its one mana more expensive brother, Vizier of Tumbling Sands, which we also can cycle and still untap one creature. We also play two copies of Kiora, Master of the Depths, because it can untap a creature and a land with its +1 and can also generate card advantage with its -2.

Willbreaker, Arcanis the Omnipotent and Experiment Kraj all cost 5+ mana so we got plenty of mana dorks, so we don't need to play 26 lands, with Birds of Paradise and Elvish Mystic.

For protection we got three copies of Mana Leak, as our Willbreaker is easily bolted and we would like to protect our win-con.

The land count is at 25 with 4 Hinterland Harbor s and 4 Yavimaya Coast s. The pain land might seem a little questionable, but I don't like paying 50€ just for the manabase of my decks.

The deck is pretty budget, only costing 50€ on cardmarket.
