Notes & Combos
I always try to dump Reflection of Endymion with Magician's Soul to use its spin effect when special summoned with Selene. If I already have Reflection of Endymion in Hand my Priority of Cards to dump looks as followed: After ITV: Garuda > Cerberus > Jackal King / Jackal Before ITV: Cerberus > Garuda > Jackal King / Jackal
This Deck is very resilient and can Boardwipe multiple times using Worldsea Dragon Zealantis. Use Promethean Princess to go into Amblowhale for free and you can use Amblowhale to Summon Zealantis or use Apollousa if you don't need her anymore.
I personally take the Maxx "C" challenge most of the time. You can Search Amorphage SLoth with Beyond the Pendulum and Pend Summon him. You can also keep your normal Summon to Tribute summon him since you don't need your normal summon.
You can swap out the Endymion Field Spell Citadel for Secret Village or Necrovalley if you want.
If you wanna cut down / change the count of any cards in this Deck to fit other ones you'd like to play then I'd recommend the following individual counts:
Main Deck:
1-2x Jackal 2-3x Jackal King 1-3x Ceberus 0-2x Reflection 0-3x Magister 0-1x Citadel 0-1x Allure of Darkness 0-3x Into The Void 0-1x Soul 2-3x Institution 0-1x Amorphage 0-1x Garuda
Extra Deck:
0-1x Starving Venom 0-1x Promethean Princess 0-1x Spright Elf 0-1x Amblowhale 0-1x Zealantis 0-1x Exceed The Pendulum 0-1x Underworld Goddess 1-2x Selene
