discard a card at random mtg Cube: Top 10 Effects o:discard and o:random · Scryfall

Whenever a player casts a spell, if no mana was spent to cast that spell, this enchantment deals 5 damage to that player

The result is a faster draft experience that introduces new layers of strategy in card selection and deck building, while making it appealing to both newcomers and seasoned players

Even though Dalakos generates mana for your equipment, Id rather run a card like Cloak of the Bat in my main deck and choose a more impactful commander

My Verdict: Trepanation Blade is a funny card for casual magic and is hilarious when it actually works but please dont use it in serious matches

While a very efficient tutor for the mana cost, sacrificing a creature was a pretty big ask when the Commander format was slower, running more akin to a battlecruiser environment full of big creatures slugging it out than the much more intricate version we play today
