Plus, whenever any player, including yourself, casts an instant or sorcery, you get to draw a card
Iymrith, Desert Doom I would like to introduce you to my friend strictly different Dragonlord Ojutai
Whenever Kroxa enters or attacks, each opponent discards a card, then each opponent who didn't discard a nonland card this way loses 3 life
This was during the closing days of Urzas block, and green and Elves were very strong, and you had powerful cards like Priest of Titania running around
Unlike white and black, green doesnt return cards from the graveyard to play
This means that if your commander gets destroyed and you let it go to the graveyard (or any another zone), you wont have to pay the tax if you end up casting it from there
