Security Bypass

The evasion clause is doing double duty, and the second job is the interesting one. Unblockable is old, but tying it to attacking alone imposes a real cost: to make the enchanted creature connect, you have to commit to a lone attacker rather than a board-wide assault. That restriction is what pays for stapling connive onto the damage trigger. Every connection filters your hand and, if you pitch a nonland, grows the creature, so the Aura becomes a self-fueling loop that rewards a hand full of expendable cards you would rather dig past. The counter accretion is the payoff that keeps the two-card investment from staying fragile: land a couple of hits and the body has outrun most removal math, while your hand quality climbs each turn. But that reward is strictly back-loaded, and the design owns the danger rather than mitigating it. The turn it resolves, the Aura advances nothing on its own, so the classic two-for-one risk (a removal spell on the enchanted creature costs you both cards for zero value) is at its worst before the engine ever fires. You are buying a delayed, compounding return and accepting the window in which a single instant undoes the whole plan. Connive is what keeps this from being a vanilla "can't be blocked" enabler: it converts an evasion trick into a card-selection engine that happens to end games, and the "attacking alone" line reads as a drawback precisely because it functions as the enabler.
