Hazoret the Fervent Besides being indestructible, Hazoret the Fervent is a 5/4 haste that allows you to turn any card into damage
At a cost of 3GG, you get a 5/5 creature with Trample and Haste, which is good value
Additionally, [lucky] players will suddenly come into all kinds of money when they pull Goyfs, Cliques, and Bobs in their MM2015 packs, not to mention a lineup of Eldrazi
It also had the advantage of being more elegant than its mirror card Undermine, as it was a simple combination of Healing Salve and Counterspell for the combined price of both of them, and while the strength of the colors meant the ranking here goes the other way, Absorb shows how it's more important to get what you need rather than what is technically more valuable
In fact, the right side of the dungeon (Scry 2, Make a Treasure, and then make a 4/1 with menace) can help you rebuild after one of the creatures dies and gets you back on board, not to mention the fact that you could also just cast another Intiative creature and progress the dungeon that way
