Deceptive Frostkite

Every clone effect answers two questions: what it copies, and what the copy costs in flexibility. This one pays with a hard floor. It can only enter as a copy of a creature you already control with power 4 or greater, which turns a blue two-drop into a conditional duplicate of your own best body: not a Clone pointed at whatever the table fields, but a mirror aimed strictly at your own heavy hitters. Because it copies rather than targets, hexproof or shroud on that creature is no obstacle, though the power gate does most of the limiting work anyway. The rider is where the type line earns itself. Whatever it copies enters as a Dragon in addition to its other types, and it keeps flying, so a grounded four-power beater becomes an evasive Dragon for two mana, and any effect keying off the Dragon subtype gains a trigger it never had to build toward. That is the real axis: less a value clone than a subtype-and-evasion converter, taking a creature that already earned its slot and stapling flight plus a tribal tag onto the duplicate. With no legal power-4 body in play, it falls back to the printed 1/1 flier, the honest price of a conditional enter-as ability rather than an unconditional one. The power-4 gate rules out generic copy-engine abuse; the Dragon conversion means it never sits dead in a scaled-tribe shell hungry for more bodies on wings.
