This is particularly useful in sacrifice decks that benefit from killing their own creatures
During each game, you have access to a maximum of three sticker sheets
You should look to end the game quickly with a card like Thassa's Oracle or Laboratory Maniac once you have a combo set up, whether its infinite turns or infinite card draw
This card doesn't start in your deck but in a special "Command Zone." You can cast your commander from this zone, and if it would die or be exiled, you can return it to the command zone to be cast again, though it costs an additional two mana for each subsequent cast
Sure, you'll have to hardcast it but that works here
Lightning Bolt is my go-to example of a secretly modal card, as it has three different modes: Deal 3 damage to target creature, 3 damage to target planeswalker, or 3 damage to target player
