You realize "removal" counts as death right? If he didnt die then you shouldnt be losing the game. Removing him from the game doesnt cause you to lose right now.
My suggestion was to make it so removing him from the game should cause you to lose, not him dying as killing him is simply too easy to do right now.
So in other words, what you're saying is, you want to make an already extremely risky card even worse? That's just absurd and unnecessary.
When someone says "removal" in a card game it is different than "Remove from the game". Removal is a general word used to describe kill spells or anything used to get rid of something you dont like including "remove from the game" or transform effects etc.
Currently Grimmish only causes you to lose on death or exchange control.
Im saying make Grimmish cause you to lose on remove from the game or exchange control.
Currently there are less ways to remove cards from the game than to kill them. Under my suggestion if he dies, you keep going. If opponent then graverobs him, you lose. If you overcharge him, you lose. Opponent death rays him, you dont lose. Opponent kidnaps him, you lose. Opponent blocks him and he dies, you dont lose. Opponent box of wonders him, you lose. You block with him and he dies, you dont lose. Opponent kills him with Kali, purifier, you lose. Opponent deals 20 damage to him and he dies, you dont lose.
