Chart a Course

The conditional discard is the whole design idea: two cards for two mana is a rate blue does not normally get for free, and the clause that prices it (you keep both only if you committed to combat that turn) is what ties the spell to a tempo plan rather than a control plan. Read it as Divination that rewards aggression. A pure draw-go deck pays the full cost, discarding the worst card and netting card-neutral selection rather than advantage; a deck that has already turned creatures sideways gets the genuine two-for-one with no strings. That makes it a deliberately partisan effect, slotting cleanly into the aggressive-blue archetypes (tempo, spell-based aggro, anything attacking on curve) and reading worse in the decks that want raw card advantage at instant speed. The sorcery timing reinforces the point: there is no holding it up on the opponent's turn, no flashing it in as a combat surprise, which keeps it honest as a proactive refuel rather than reactive insurance. It is one of the cleaner examples of a card-draw spell whose ceiling and floor are set entirely by your own game plan, asking you to have already done something on the board before it pays out at the top end.
