Tower Geist

Card advantage with a body, priced for the part of the game where neither feels expensive. The enters trigger digs two deep and hands you the better of the pair while binning the other, which means the choice it offers is constrained: you take what you most want now and accept that the second card is gone, not shuffled away or left for later. That graveyard clause is doing quiet work for blue's recursion and flashback shells, where a card pitched to the yard is a card you can still reach. The flying 2/2 is the part that justifies the whole package: this is not a sorcery that replaces itself, it is a creature that replaces itself, blocks evasive threats, and chips in for two while you spend the rest of your turns ahead on resources. That distinction matters more than the modest stats suggest, because a body that stays on the battlefield keeps generating pressure long after the card it grabbed has been spent. Blue has built this exact effect again and again, turning a single card into both a board presence and a refill, an attrition payoff rather than a tempo one. The selection is shallow and the rate is fair rather than generous; what keeps it relevant is that every line of text pulls toward the same goal of never running out of gas.
