Into Tulgey wood

When this enchantment enters the battlefield
Delude 3 (look at the top 3 cards of your library.
You may put any of them face down as 2/2 colorless
delusion creatures. Put the rest of the cards back in
any order.)
{1}{u}{g}: Rationalize 6 (Exile a face down delusion
creature you control. Until the end of this turn you
may cast that card from exile. It gains "You may use
mana of any color to cast this spell," and its mana
cost is reduced by 6.)
