Glint Hawk Idol, without question, is better than Angel's Tomb. The fact that it's an artifact that survive board sweepers and you can activate it without any help is very important.

I do agree that its better but I didn't want to play it since it would look like a copy of my friends deck.thanks for the suggestion though. Before any tourneys I'll definitely switch them out

Angel's Tomb is probably going to end up a lot slower than Glint Hawk Idol, unless the meta begins to slow down before rotation.

Speaking of the meta though, I would personally consider changing Hellrider to Hero of Oxid Ridge simply to punish decks that rely on Lingering Souls and the like. Plus if budget is a problem, thankfully he is a lot cheaper than his Bladehold counter part. ;)

Personally I prefer the Hellrider just because if I drop him turn 4 he's devastating
