Electrodominance

If the target is dealt lethal damage this way, it will still be on the battlefield while you cast a spell from your hand. It won't die until after Electrodominance is finished resolving. If any of its abilities trigger while you cast that spell, those abilities will trigger but won't resolve until after the target has died.

If a spell has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

Effects that allow you to cast a spell don't allow you to play a land.
