TJ, the Chronicler

Haste, menace

Whenever you cast your second spell each turn, exile the top card of a library. If it's a creature card,
TJ gets +X/+0 until end of turn, where X is that creatures power. If it's an instant or sorcery spell, copy it. You may cast the copy this turn and mana
of any type can be used to cast it.
