Blue Sun's Zenithcard_draw$4.59Very close functional match: an instant-speed X draw spell that targets a player and can act as a win condition or massive draw engine. It even shuffles back into the library for repeat use.
Pull from Tomorrowcard_draw$1.98A scalable instant-speed card draw spell in blue that converts extra mana into a large hand refill, similar to Stroke of Genius. It draws you cards directly rather than targeting any player.
Mind Springcard_draw$0.54Same basic X-draw role and mana profile, letting you sink mana into a burst of cards. It is sorcery speed instead of instant, but the effect is very similar.
Braingeysercard_draw$80.89Classic predecessor to Stroke of Genius: an X blue draw spell that can target a player to draw cards. It is more restricted by older wording but fills the same functional slot.
Prosperitycard_draw$4.59An X-based mass draw spell that scales with available mana and can refill multiple hands. It affects all players rather than one target, but serves a similar blue draw-sink role.
Whispering Madnesscard_draw$3.06Not a direct X spell, but it is a blue card-draw-based hand refuel that can generate substantial cards in the right shell. It plays a similar role in long games as a scalable draw engine.
Recallcard_draw$0.41An instant-speed blue draw spell that converts extra mana into cards and can be aimed at a player. It is narrower and older, but functionally close to Stroke of Genius.
Gigadrowseutility$0.23Not card draw, but in blue combo/control it serves a similar late-game mana sink and can secure a window to resolve draw spells like Stroke of Genius. Useful as a functional support comparison in blue instant-speed planning.
