Well, being that Raziel is a mainly melee based fighter, he would have an extremely hard time winning against a mainly long-range attacking foe, as Samus is considered with her arsenal of firepower. Raziel can shift all he wants, but it will only take Samus 2 or 3 times max to realize that when he comes back, he will always be in the same place. Bang bang, dead.

Raziel's glyphs are way too weak to do any real damage to Samus, and as stated in earlier fights it would merely stun her, if it actually landed... Even so, Samus could always screw attack when they are approaching, hence neglecting their entire premise since only extreme power attacks can halt a screw attack, as was established many a times in earlier rounds.

I honestly don't see how Samus could possibly lose this one. Raziel is strong, but his constraints will prove too insurmountable in this battle. He needs broader attacking abilities to pull out a win, which from what little I know about him, he simply doesn't have.
