Sev Baan, Resistance Crafter

Spells you cast have Improvise (Your artifacts can
help cast this spell. Each artifact you tap after you're
done activating mana abilities pays for 1.)
Whenever you Improvise, for each artifact tapped
this way, look at that many cards from the top of
your library. Put one in your hand and the rest
on the bottom of your library in any order.
"Never has the expression "to squeeze aether from
stone" been taken so literally" -Dovin Baan
