Here are a few other suggestions.
Tar has given some nice suggestions for equips, so here are a few more.
GM Phoenix Letterman - ggFTW Trickster Wiki
GM Loki's Letterman - ggFTW Trickster Wiki
Etoile Pendant 130
Badge of Gratitude (Magic) - ggFTW Trickster Wiki
Golden Ice boy T4 150
Sir Galleon 150 (kind rare now)
Fuzzels (130/160/190), if you MA comp these, they are comparable with crystal pets.
Rally Towel 60/180
Look for ingames things with high MA or DP with 3 slots. Ults or requiems are fine. Use the wiki to work out the stat ranges. 80% of max is sufficient. Refine to lvl 4 ish.
Altiverses are once an option, but I think there will be many posts about them to come. i am just trying to say altiverses are not the only thing around. tar has eluded to this as well.
In terms of prioritising any myshop you may get I reccomend things in this order
Ingame weapons can be better than myshop ones. Sprints are ok too.
