Darkness is a fun one -- the spell effect does have the idea of sudden darkness happening in the midst of combat (hence creatures still being 'tapped') and causing all the attackers to miss their mark (hence no damage is dealt)
In fact, cards such as Rite of Passage and Rhythm of the Wild are, surprisingly, worth more as non-foils than they are as foils
I will personally miss the Normal Rares
Sacrifice those tokens at end of combat. The real stinger, though, is the final part, which reads: Whenever Shredder deals combat damage to a player, that player loses half their life, rounded up. The idea is that your Shredder, or its clones, will do damage to an opponent and halve their life total - but if you get Bloodletter of Aclazotz on the field, you can finish them
The expressive watercolor-style background and detailed character line-work elevate this card into a true piece of modern TCG art
