Barely-Functional water pile

This is mainly a go second deck, mostly as a way to deal with, currently, barely hit tenpai. Odds are you're gonna open at least one of the many go second cards in the deck, mostly spells like "Ultimate Slayer" "DRNM" and "Forbidden Droplet".

Very Important Warnings about this deck:
-You have basically no backrow removing spells, your best backrow removal are either monster effects or heartbeat.

-Supay locks you into synchro monsters, so make sure to do every possible tearlament play before using her.

-Marincess Coral Anemone locks you into water, so make sure to use her AFTER getting kitkallos on the field or graveyard.

Card selection and ratio logic:

-Since this is a go second deck, i opted to put more Icejade manifestation and less Icejade cradles, since they let you special summon from the deck and let you summon an easy lvl10 synchro.

-Grief is a good starter, but it only works if you have at least 1 aqua mosters in the had, so I put 2 copies instead of 3.

-Mereologic Aggregator is just there as a target for ultimate slayer.

-Small World basically lets you access any engine in the deck.

-Ash is just there because of Maxx C and as a Cross out target.

-Very few hand traps because i value draw power, and they hurt consistency.

-Very few traps because traps are too slow, specially in a going second deck where you don't have the first turn to set them.

Testing:

I'm considering replacing some cards for Ghost Sister, and Mulcharmy Purulia, since these are good hand traps that can be used as discard fodder for Aegerine Ran and Tidal. Not to mention that Purulia can also be used for tearlaments fusions.

I've also considered removing Zep in favor a second Scheiren to increase the probability of milling her after fusion summoning with Havnis.

Since Icejade Manisfestation doesn't lock you out of anything, you can replace a card in the extra deck with a Baronne de Fleur, and use Aegirine with Aegriocassis to summon her.

Tips and tech:

-Tidal can send any  card from your deck to graveyard, can bring it self back by banishing. it's perfect for ghoti and tearlaments.

-Cross out can banish a ghoti monster and bring it back next turn.

This the first time i've tried to build a deck, and as you can imagine trying to make a pile that mixes so many engines while also trying to make it a viable deck is not an easy undertaking for a beginner like myself. Any and all criticism is welcome. Thanks for giving my deck the time of day.
