Into the Fray

Point at a creature, force it to attack, and then watch the spell resolve into nothing: there is no permanent left on the board to enforce the compulsion, no body that punishes the attacker, just a one-turn shove with no follow-through. That is why almost nobody would pay a card for the bare clause. The splice cost is the entire pitch. As an Arcane instant, this is built to ride along with another Arcane spell you were already casting: as that spell goes on the stack, you reveal this from hand, pay the red, and a single act both forces a creature into a hopeless attack and (assuming the host does the damage) answers it. Splice does the work that makes a marginal effect worth holding: you are no longer spending a full card on "this must attack," only adding a clause to a spell that already justified itself. What undercuts the appeal is that the payoff lives entirely in your hand, not the battlefield: it needs a steady supply of Arcane spells to graft onto, and it needs them at instant speed during the combat window where a forced attack actually matters. Without a host to splice through, the card collapses back to its lone line, a combat trick whose entire value depends on a target you want dead or tapped out and a separate spell ready to finish the job.
