When Euroakus enters the battlefield, create a number of 1/1 blue Human Wizard creature tokens equal to the number of differently named lands you control.
{4}{G}{U}: Draw a card for each Wizard you control. They each get +1/+1 until end of turn for each card in your hand.
The Commander RC has ruled that if your name is printed on the bottom of a Heroes of the Realm card, that card is legal for you in Commander.
