Gripstis, the Hidden Ruler

Deathtouch
At the beginning of your first main phase each
turn, exile the top card of each players library.
You may cast permanents exiled this way until
end of turn and may spend mana as though it
were mana of any color to cast them. Then add {1} for each land exiled this turn.
"Let the merchants believe they rule Finektis, it makes
them easier to manipulate that way."
