indominus rex mtg card When Indominus Rex enters the battlefield Indominus Rex MTG Proxy: Hand-Colored

In terms of Constructed play, I cant imagine this will make a splash in eternal formats like Modern or Legacy

If you have low mana costs, lots of ramp, rocks and reducers, or don't need to cast your commander several times, you can lower the number of lands in your deck
