No, this just destroys the land
While it can be fun to pick up an under-represented type say, salamanders and try to carry it to the top, I actually find these elite typal decks to be the most fun
Commander players often dont pack much in the way of graveyard hate, so Im all about cards that can come down early to deal with reanimation targets and the like and then provide a big upside later in the game
I wouldnt suggest in putting more than 2 copies of this card in one deck, but I find it much more powerful in the mid to late game when Mana Leak starts to lose its power
If one of those creatures can't attack its owner that turn due to a spell or ability (such as Chronomantic Escape), you may have it attack another player, attack a planeswalker an opponent controls, attack a battle an opponent protects, or not attack at all
