A good way of Trade In use just like D Draw IMO.
#1: DMoC : Obvious choice. The most used LV8 monster right now
#2: Mystic Beast King - Barbaros (OCG card): This one I would run 3x in a deck that wants to abuse 3x Trade In. It's a LV8 monster that you cano normal summon without any tribute. It's a safe 1900ATK beatstick if you don't have Trade In.
#3: Ritual monsters: The main thing is, these monsters can be SEARCHED, unlike other LV8 monsters. This is big. I mean, the thing that D Draw is broken is that D-Heros can be searched by Stratos, and thus the dreaded +2 combo of Stratos + Malicious + D Draw. So in this case, use Manju/Senju to search a LV8 Ritual Monster, and then use Trade In to discard it to draw 2 cards. That's a +1 since that Ritual monster was searched out by a monster that's already on field. Probably something like a Demise deck or some other random Ritual LV8 monster can be abused with this.
#4: Special summonable LV8 monster: The example I can think of is Doom Dozer, and the 2 Sky Scourage monsters. If you don't have enough monsters in grave to RFP to special summon them, then just use Trade In to draw 2 cards and fuel your graveyard.
#5: The Creator/SPoN: These guys, got support of being special summoned while they are LV8. SPoN got way better support, since it can be special summoned from deck, and the support monster can be searched with Apprentice Engine. But still, with Trade In, you don't have to worry about 3x SPoN dead cards in hand. Also, with The Creator, you can use it's effect to special summon those LV8 monsters you discarded with Trade In, and ALOT of them are good when special summoned and alot better then tribute summoning. (e.g. DMoC)
--------------
And also, in a deck that runs a load of LV8 monster, I would also recommend 2x Metamorphosis since it can be abused to get Cyber Twin/Gatling/Jumbo Drill.
I hope to create a LV8 "Fruit Basket" deck with 3x Trade In soon
