Rammas Echor, Ancient Shield

Oracle text

Whenever you cast your second spell each turn, draw a card, then create a 0/3 white Wall creature token with defender. At the beginning of combat on your turn, creatures you control with defender gain exalted until end of turn. (Whenever a creature you control attacks alone, it gets +1/+1 until end of turn for each instance of exalted among permanents you control.)
