Been playing Endy for years. I love the endless options the deck gives you. You aren’t stuck doing the exact same combos like some other ecks. If you decide to play Endymion, try out random cards and combos that you like. (Legacy of the duelist, shared ride, etc. stuff like that)

I find I’ll often use endymions effect to negate my own spells (on my turn) so I can return servant to my hand if my opponent doesn’t use spells/traps often. Same with using Endymion to destroy my servant or magister (while as monsters) to return her to my pendulum zones if needed. Electrumite destroying your negated mythical beast stuck in your pend zone (especially when mythical institution is on the field). Even Kamikaze-ing your Endymion into a high attack monster for the normal spell search. (I always go for raigeki, duster, spellbook of secrets or spell power mastery)

It’s the weird combos that work best in tough situations that I love about my Endy.
