Let's get out of good card territory for awhile and discuss a rather questionable card, the Altar of Chaos. Well obviously by the orb and power cost, this card is definitely made for PVE. I find it hard to use, because during this time of phrase, you would want more big scary creatures to dominate the battlefield rather than sacrificing them to this in order to obtain a rather good AOE explosion. It almost seems futile though that in Battlegrounds PVE depending on the difficulty, enemies tend to have more and faster spawn rates. This card can only pull off a temporal removal and gathering units to sacrifice to this card is so pointless. Why is it pointless? Well, I believe that having more units to go and attack is better than a 250 power cost building. Now if it actually did damage without me having to reactivate it all the time, sure why not. Unfortunately this card falls down due to it's lack of consistency, sure you can get 1500 damage off without having to sacrifice a single unit, but 1500 damage is not that much in later levels and instead requires more spell casting and large monster grouping. The only way to get it above 1500 damage is to sacrifice units to this card, but during the late phase of the game, why would you? And the damage scales with the health of the creature, so yes sacrificing some dark elves or whatever that is not a T3-T4 monster not including a Harvester, are the only option for making this card deal useful damage. The max damage is only 9000, which I seriously doubt anyone would do and after shooting off a charge, it has to reload, and it did not specify how long it has to recharge for. Also one last reminder, this card deals the damage to hostile and friendly, so yeah, it would of been like decent if it only hurt enemies, but............you know. Give rating here!
