I'm not reinventing the wheel or anything here, I just figured I'd post my current list that I've been having some fun with.
Step 1: Evil Eye, if you've got Serziel in your hand you could try summoning him/her. Doing so allows you to grab whatever Evil Eye you want which could be Basilius or Selene or even the Field Spell if you've got Selene already.
Step 2: Unchained, I'm not to sure about the names but you want the traps to be in your hand, plus a way to destroy them so that you can use their effects. Aruha is the one that can Special Summon itself by destroying a card you control (maybe the trap card? hint hint).
Step 3: Now that you've got Serziel on field plus Aruha and whatever you summoned off the trap card you destroyed (or spell) You can summon that Basilius you grabbed or activate the field spell to get one. That's 4 monsters ready and waiting to be used for Link Summoning. Make the Blue Dog using your summon from the trap + Basilius or Aruha, equip the Eye of Selene to Serziel and use whatever other cards are in your hand to bolster your defenses.
This end board definitely won't win games or lock your opponent out of anything too important but on their turn if they Special Summon you can Link their card away with the Blue Dog and you've got Serziel who is immune to things while equipped with Selene so you can use their effect to destroy another of your opponent's special summoned monsters, which will make it so you need to destroy a card on your turn (per Serziel's effect), luckily if you've got another Unchained trap or that Aruha still around you can summon another Unchained from the deck.
Every time you use Serziel or another Evil Eye spell/trap your Serziel gains 500 ATK and you lose 500 LP, this is how you can make Big Serziel using a monster with 2600 or more ATK so that Big Serziel can attack twice.
Sorry if I've not explained things well enough, but I think this deck is more fun to experience yourself rather than having someone explain every step to you.
Enjoy!
