Rulings
If you exile a land card and a nonland card, you'll create a Dinosaur token, then a Treasure token.
If you exile two land cards, you'll create only one Dinosaur token. Similarly, if you exile two nonland cards, you'll create only one Treasure token.
You pay all costs and follow all normal timing rules for cards played this way. For example, if one of the exiled cards is a land card, you may play it only during your main phase while the stack is empty.
