Commandeerutility$5.12A flexible blue instant that can redirect a spell's impact by changing control of a spell on the stack, similar to Insidious Will's modal stack-interaction play pattern. It is a higher-end blue interaction piece rather than a direct counterspell replacement.Reverberateutility$2.83Like one mode of Insidious Will, it copies an instant or sorcery and can retarget the copy. It fills the same spell-copying role at a lower mana cost.Twincastutility$4.35A cheaper blue instant that directly copies an instant or sorcery, matching Insidious Will's copy mode closely. It is narrower, but very efficient in spell-heavy decks.Forked Boltutility$0.36This is not a stack-control card, but if you are looking for cheap blue-red style spell interaction alternatives, it reflects the kind of low-cost spell play that pairs with copy effects. In mono-blue, the closest functional equivalent is still a cheaper spell-copy card.Narset's Reversalutility$2.52A highly flexible blue instant that copies a spell and returns it to hand, often functioning like a tempo-positive version of Insidious Will's copy mode. It can also effectively counter some spells by removing them from the stack.Misdirectionprotection$28.45Similar to the 'choose new targets' mode, it redirects a spell or ability by changing its target. It is more specialized, but often plays like a premium blue protection trick.Spell Swindleremoval$3.03Another blue instant that interacts strongly with the stack, countering a spell and generating value from it. It replaces Insidious Will's modal flexibility with a more expensive but payoff-heavy counterspell.Arcane Denialremoval$2.53A clean blue counterspell substitute that handles the counter mode of Insidious Will at much lower cost. It is less versatile, but far more efficient for straightforward permission.
