The IMMORTALS (Gold Saver Edition)
This is a low-micromanagement mega-deathball PvE build using 2 "reviving" tanks and 2 healers. You don’t need talents early on with this build but Harvest Golem will stun twice with his talent and Core Hound can resurrect from unlimited range. It’s great early in when you aren’t leveled up high enough for tougher levels. It has worked for me to at least sigil level 50 and some higher. It’s also great for bigger maps that buy you time to deploy tank and healer without much gold yet. You’ll survive through pushes without losing much units thus not needing a lot of gold right away. For some maps you will probably have to change some units depending on the map. Troll, Pyromancer, Quillboar, Earth Elemental are decent replacement for range, AOE, tanks. This tank and healer combo is pretty self-sustaining but you'll need to support the tanks with AoE since they are susceptible to swarms. Obviously you'll need range and unbound to help take out enemy range units or stop units on bridges.
