If colorless cards could draw from strategies that are usually associated with specific colors, itd allow the rest of the color pie access to things that it usually shouldnt have
I appreciate you trying, but
If another player says Ill do such and such if you dont attack me, then Ill take that to also mean not Comet Storm-ing them into oblivion or nuking their battlefield
Play your cards right, and when your instant and sorcery spells head to the graveyard, they won't stay there for long , as there are creature abilities in play that can get them back in your hand for another round, much to the dismay of the other players around your table
Whenever a land enters the battlefield under its owner's control, Bloodghast's controller may return it from their graveyard to the battlefield, meaning even if it is destroyed, it will likely be back soon
It wasnt always full trees though
