I play 3 decks : a Neo-Spacian one, which look like the one posted on this site with Last Gamble. A UFO-Hero deck, with 3 EH Ocean, 2 EH Woodman, 2 King of the Swamp, 3 UFORoid and Terra Firma / UFOroid Fighter in the Extra deck. And a Tempest / Flame Wingman deck, with Avian, Burstinatrix and Bubbleman. There are Tier 2 decks, but I like them.
It's just a good way to summon a beater. With Ocean, UFOroid Fighter has 2800 ATK, for example. UFOroid is just a fusion material in this deck. It's just a fun deck in which you can easily summon UFOroid or Terra Firma turn one. It's good against LD or SD, but not in PVP.
Looking at possible E-HERO decks now. Without three copies of Clayman and with the holes in potential fusion cards, the archetype is still too weak to make tier 1. Without Grand Mole, Grand Neos, Air Neos, "shining" upgrades, Nova Master, E-Emergency Call, Hero Signal, and Reinforcement of the Army I'm not sure I see the potential being reached. Will have to see what they add.
One card remains, could add a number of possibilities: Wroughtweiler, Fusion Recovery, O - Oversoul, an extra Fusion Weapon, Run a pair of SRH and a pair of EC, or De-Fusion. I'm running De-Fusion for kicks, but will see how the deck stacks up in reality.
