Kadena's Silencer

This land enters tapped. T: Add U or R.

This land enters tapped. When this land enters, you may put target creature card from your graveyard on top of your library. T: Add B.

Creatures can't attack you unless their controller pays 2 for each creature they control that's attacking you.

Draw three cards.

Exile the top three cards of your library. Until the end of your next turn, you may play those cards. If this spell was cast from a graveyard, you may play cards this way without paying their mana costs. Flashback 7R (You may cast this card from your graveyard for its flashback cost. Then exile it.)

(T: Add R.)

T: Add CC.

Whenever a face-down creature you control enters, you may search your library for a basic land card, reveal it, put it into your hand, then shuffle. Whenever a permanent you control is turned face up, if it's a creature, it gets +2/+2 until end of turn.
