Once per turn, when your opponent activates a Spell Card or effect (Quick Effect): You can place this card in your Pendulum Zone, and if you do, negate that effect, then, if you placed this Ritual Summoned card in the Pendulum Zone, you can Special Summon 1 "Odd-Eyes" monster from your Extra Deck
You can play one of these either as a Clearwater Pathway and be able to generate blue mana, or as Murkwater Pathway, a land that generates black mana
Every time an opponent draws a card, they either pay 2 or hand you a Treasure with a much needed mana ability
Im not certain if Curios always appear in this position or if they could be elsewhere among the Ordinary cards, but I now pay extra attention to the first card after the Unique/Elite slot
I dont want exposure like this, its the last thing I want, Greenbaum told the paper
What's done is done, just know that putting Mana Crypt in your casual coin-flip deck meaningfully raises the power level of your deck.
