You already know what Traptrix does and how broken Sera is so let's get down to business.
With this new wave of support Traptrix has gained a great tool of interaction in the form of Holeutea and a great Xyz monster which allows them to search for any traptrix monster while also stealing your opponent's graveyard/banished monsters, obtaining a reliable form of removal and OTK tool easily accessed with Aussa + Maxx C in the form of the new Link 3 Atypus.
Your combos will usually depend on your normal summon starter and eXceed but for most hands, one Traptrix monster + any normal trap will land you into a Sera + a rank 4, however with a good hand you are capable of going into much more, i.e.:
NS Pudica to grab Garden > Link into Sera > SS eXceed making Rafflesia > normal summon Dionaea bringing back Pudica > Sera eff to set Holeutea from deck > Holeutea eff to discard a normal trap (in this case a Hole card) and SS herself > Sera eff to SS Dionaea from deck > Dionaea eff to set the Hole trap discarded with Holeutea > Xyz with Holeutea and Dionaea into Pinguicula > detach Holeutea search Arachnocampa > SS Arachnocampa and Xyz into 2nd Rafflesia (soft OPT) with her and your leftover Dionaea.
This board has backrow protection with Arachnocampa and allows you to activate two Hole cards from Deck using your two Rafflesias with her added targeting and destruction protection, attaches a monster sent to the GY/banished with Pinguicula, SS Pudica from the GY to banish an opponent's monster and SS Myrmeleo from the deck with Sera to destroy your opponent's backrow.
Although my explanation might have been hard to follow, the example given shows what the deck can do with the best of openings, however the deck still very consistently ends on Sera + Rafflesia + Pinguicula with just a Traptrix monster + Holeutea and in the case you get Maxx "C"d, simply ending on a Sera with whatever backrow you have (Dimensional barrier being the strongest one Vs Branded and Tear) may be enough to stop your opponent in their tracks. On your subsequent turn, Allomerus allows you to summon a monster destroyed by Atypus or a Hole card or banished by Pudica in order to threaten lethal more easily.
All in all I've had a great time playing this deck, the ability to play a control oriented playstyle while also having the possibility to combo is very satisfying and the ability to play 3 Evenly matched is extremely strong while still being good going first as fodder for Holeutea. I have climbed all the way from Plat V to Master V so that goes to show this deck can still put up a fight and find success.
