Space magic. Obviously.
Or we all remember that Tommy is a close personal friend of the guy who created the power coins.
As I pointed in another thread - my theory uses Burai's lifeforce draining plot from Zyuranger. When Rita created the Green Candle, it didn't just drain Tommy's powers, it drained some of his lifeforce. By giving the Dragon Shield and the Dragon Dagger to Jason, Tommy managed to save a small bit of his powers and the little lifeforce that the Green Candle took from him, this, preventing his own death. Then, Zordon re-charged Tommy's Green Power Coin, which temporarily gave him his Green Ranger powers back. This event was followed what we saw in "Green No More, Parts I and II". Lord Zedd created the Green Crystal, which stripped Tommy of his powers once again and once again, of some of his lifeforce as well. When Tommy touched and smashed it, he teleported back to his friends, saying to the Rangers that he will be able to go trough one last fight as the Green Ranger. He later became the White Ranger and the Red Ranger on two occasions, however, deep down, he still wished he still had his original powers back. That wish grew stronger and stronger in him every time he came back - first as the White Ranger, Zeo Ranger V, Red, Red Turbo Ranger and Black Dino Thunder Ranger.
While he was happy he was still able to be a Ranger after loosing his original powers, he just wasn't completely happy with the new powers and everything. And that led him to have that dream in the coma in "Fighting Spirit" - yes, he was fighting for his life, but subconsciously, he also fought for the revival of the Green Ranger powers. So when his three Ranger forms (I guess he didn't care for the Turbo powers, because he did give them away to someone else half way trough that season) gave him pieces of his Dino Gem in his dream, his Green Ranger form also provided him with a way to restore the lost powers. Tommy then visited the same place where he fought himself in his coma dream and there, he found a power source, capable of restoring lost Ranger powers. Enter Hayley and... you have 1 MMPR Green Ranger in the Legendary War.
Spoilers. They roomed together in College.

Or just use the Ranger Key theory (more plausible and likely) as I stated in an earlier post. Though not a bad theory (actually it's well thought out), part of me knows they wouldn't go so far into lore as that to confuse the children. So they'll probably just explain how the Ranger Keys were made, though they kinda already hinted at it in Megaforce, and boom, he can turn into any Ranger he pleases to suit any given situation.

Im back :)
Actually that would be awesome but SK did state that he fully restored the powers. So Adam or SK didn't have an encounter with evil Black and just restored the busted up Morpher from Always a chance.

Amit, despite how flawed FR was, is a logical writer and It makes sense that he says it because It (should) puts an end to the senseless bickering that's been taking place in the forums for years since FR aired. The amount of blatant ignorance (despite how many pages online that can verify this) is actually pretty Lol worthy.

^I am a firm believer in that logic.
