Time Walk (Turn) 6
I often see people board down to ten dredge cards, which I dislike, as the two-mana enablers rely on you to have a dredge card in your hand to discard, and youre often sideboarding out an Otherworldly Gaze as well, which acts as a way to find dredge cards when you dont have one in your opening hand
Additionally, you should not use or buy fake cards
You can give your stuff a +1/+1 counter and flying for 0 loyalty, and then -3 to destroy a creature an opponent controls with power 3 or greater
Pretty much every cEDH deck is playing these cards anyway, so it shouldnt be hard to protect your critical spells in a Shadow deck
Each Commander deck in the set does so to varying degrees of success, but the effects on display here range from draw to damage boosts to destruction, covering all the bases
