It depends on what you already have. If you have Neos and Edgeman (Bladedge), then your collection for lots of strong E-Heroes is among doubles/triples of them and Fusions. However, there is Neos Alius, a 4-Star version of Neos with 1900 ATK and 1300 DEF. Something to definitely consider, especially since his name is also treated as "Elemental Hero Neos", making him useful for fusions should you run out/not draw any of the original Neos.
