There is a lot here. Firstly, the common scareclaw line has a point right before you make Tri-Heart where you may have two level 3s on field, you can use these to go into the biker side of the deck, or go straight to the Armored Xyz, though I don't recommend this. Goblins can get more 3s to possibly make the Armored Xyz afterwards. That is the general idea of the deck, go from Scareclaw to Goblin Biker (instantly giving your oponent a stroke), then going into the Armored Xyz portion.
For non-engine I am running some bassic cards like Imperm. I think Ghost Belle is a good fit, though I would definetely keep Ash sidded. Forbidden is a nice board breaker, but evenly is very good too. The only issue is that going second, you want to OTK with Tri-Heart so having to skip and do everything in main-phase 2 is a little rough. Also, if you're Light-heart is hit by Imperm, you can Droplet it to dodge.
Tech picks, rank 3 xyz monsters are good if you're Tri-Heart blows up somehow helps remedy your board and at least you can end on a No. 75 and Fortune Tune can be a time win con? Link Spider is to help recover from Nib which an oponent may side into. Dharc is great because he can activate your eXceed, you can easily access him with the Light-Heart or Reichheart. Heres hoping they add a dark Goblin rider, I would be increadibly happy if the Merciless was a dark instead of a water, but o-well. You can side into the Twinsaw in heavily link heavy decks and it does not impose on the Armor Xyz trap effect. I was thinking of using dogmatika punishment to send the rank 6 into the grave because it's grave effect isn't reliant on being xyz summoned, but the deck kinda struggles going second so I am updating it for that. I think it could be a neat add to Lab though? Another great choice is Dis Pater. He can summon back a Reichheart or a Visas if you go into him and then Astraloud, that is two material that you can use to make your Tri-Heart with. I am not running him because I don't have money like that. Stardust warrior is also neat because he is a recurring summon negation, plus when he is outed you can go into the Spell/Trap negate which is neat, but it requires a lot of extra deck space and is reliant on the opponent to out him, which is not the best.
Also. if you draw a Terrortop, you can have enough material to make a Goblin Biker without needing to draw two scareclaws, which really helps with the deck's consistency.
There are a ton of small synergies in this deck so I'll list a few of them:
1) Tri-Heart has a down pointing arrow and can co-link with Pheonix to net a draw. Notably, this is not the case for Unicorn, which I was considering running.
2) Xyz Armor Torpedo detaches for a draw, which if you detach the scareclaw 3s may come back with an arrival.
3) You can use Sploder as a target for Visas and then go into Astraloud if you have Reichheart, which you should always try to. Sploder has a grave effet to come back too.
4) You can discard a Visas for Forbidden droplet and go into an Astraloud that way.
5) D-Barrier can only target one of these, if Xyz, just play a brickier Scareclaw and maybe synchros plus Astraloud, if Link, get two threes, make a xyz and go into the armored xyz line and maybe Astraloud. Always maybe go into Astraloud, even if you don't get hit by D-barrier.
6) When special summoning the Goblins from the graveyard, if you do it in defense you can get three cards in defense real fast for your Reichheart which can get you a draw. Though this may not come up as often as generally Reichheart will be in play before the goblins.
7) The Full Armored attach effect can allow you to detach for a goblin's summon effect later. Though thats not the most useful, it is just another line you can use.
8) When summoning Chengying off of Reichheart and Visas, you can go into an Astraloud afterwards and immediately activate Chengying's effect banishing from field and grave.
Cons:
The deck is a little more bricky than any of these pure, the Visas, armor xyz trap, multiple bikers, and garnets like terror top suck to draw into. I am only running Visas cause I love Astraloud and you can go into Chengying.
The deck falls to Nibiru, which is why we play a Link Spider, but it can still really suck even with the Link Spider. We used to have a 5th summon Baronne, but she was banned recently.
You need multiple of the Scareclaw links so extra deck space is a little tight. I am running multiple of them for the clap back. And if they get negated or destroyed. Your ultimate win con is a Tri-Heart, the rest is to back him up.
You may run out of main monster space, in general you need to be conscious about your zones, which I am not.
End board is real elastic, peak is Tri-heart in extra monster-zone, Gabonga, Chengying, Xyz Armor Fortress, two of the scareclaws (preferably Acro and Belone) with a Sclash or Twinsaw and a Full-Armored Xyz set. This is a deck that I will be playing more of in the future and updating. Any feedback is well appreciated.
