High base atk eidolons with decent enough effects are something you'd probably want if you're using an eidolon that checks the number of matching element sub eidolons.
Horus users may want another copy of Adramelech's 2058 atk and 3 turns of unknown amount of +double, as +double/+triple effects are nice to speed up burst gauge generation.
Pazuzu/Hanuman users may want another copy of Icarus's 2094 atk and 3 turns of unknown amount of +triple.
Nidhoggr users may want...uhhh, when the original koihime collab reprint happens, does the exchange reset? Cause a 2nd Meng Huo's 2100 atk would be nice for Nidhoggr users. If not, then uh, both Amaru and Yggdrasil are sitting at 1866 atk. They're not worth a 2nd copy of in the long run since the next 3 thunder eidolons are Tartarus/Medjed/Yato-no-kami (1950/1950/1998 atk respectively). So, yea, hope that the exchange resets for a 2nd Meng Huo :/
Illuyanka/Leviathan users want that 2nd Tiamat.
Managarmr users could possibly want a 2nd St. Nicholas's atk (1950), but that summon effect is annoying. If you're looking more for raw beefiness instead of snazzy effects, then there you go. The future light event eidolons with over 1800 atk are Yule Goat (1890) and Nandi (1986). So there's room for Sphinx/St. Nick/St. Nick/Yule Goat/Nandi if you're just looking at atk. The 2nd St. Nick may be replaced by Abou (1770) if you want her dark atk debuff.
For Anubis users... your options for simple to get 2nd copies just don't have high atk. Dark event eidolons in general don't have high atk. The highest two are Delphyne (2010) and Trivia (1890). The 3rd highest so far? Apocalypse at 1680 o.o
If you really want a 2nd copy then, maaaybe Jack o' Lantern (1602) for the zeal effect? Burst gauge generation is nice as long as you can tolerate the self burn aspect of zeal. But really, you're praying to roll a 2nd maxed copy of Trivia or Delphyne.
