So many new Magic cards incentivize Commander players to make their mana curves lower and lower, Im glad to see some incentives in the other direction
Or rather, they can be, but it depends on the context
If you're new to MTG or just looking to keep your game more organized, we might suggest Flinxz's Blueprint, Old Hat Studio's Learn To, or Stephen Pena's Beginners and Organizers playmat
We won't be able to win in one turn, but this wasn't happening very often already, but gaining 10 at a time is perfectly reasonable
If at least one target is still legal, the spell or ability does as much as it can to the remaining legal targets, and its other effects still happen
You can also drop Hexdrinker on a later turn and immediately level it up to at least the "protection from Instants" level, which will protect it from Erode, Doom Blade, Lightning Bolt, and Fatal Push
