**The 70% market-implied odds favoring a price decline for the Mega Dragonite ex SIR (Ascended Heroes #290/217) by August 31 stem primarily from the imminent release of the Mega Forces Tins on August 28.** These tins feature an alternate-art Mega Dragonite ex promo alongside four booster packs, injecting fresh supply of Dragonite-themed product into the market just days before the resolution date. Traders view this as a classic supply shock for a card that peaked on post-release hype earlier in 2026 and has already shown softening raw and graded values amid broader market cooling for the January-launched Ascended Heroes set. With no major new reveals, competitive play surges, or collector events scheduled to counteract the influx, the near-term catalyst points to downward pressure on secondary-market prices for the existing Special Illustration Rare. Historical patterns in the TCG space show similar tin releases often accelerate short-term corrections for chase cards once initial scarcity fades.
