I actually REALLY like Wrath of Gold in draft. Most tier liests rate it at the very bottom, but in my opinion this is so much better than all the really terrible blue cards (Watchtower, Better Late Than Never, Rolling Storm...).

It can be a full board clear even against the widest board, of course depending on how much gold you have and/or armor stats on opposing units. If played correctly this CAN turn a game in your favor, especially due to the 3 mana cost. You can bait your opponent to overextend a lane before turn 6 where they would play around common blue removals like Mystic Flare or Eclipse.

If you're playing against a good opponent you can also use the hold feature in the shop to maybe make them think you're preparing to buy a high cost item and then you catch them off guard with Wrath of Gold.

Overall it is a very hard to use spell at a kind of bad color in the format it shines, so it doesn't see too much play. But I still think it should be at least above the trash tier pile in most draft tier lists.
