Forbidden Droplets and Dark Ruler No More are also good choices.
Anyways, here's the more comprehensive breakdown of the list and how the cards bounce off each other.
Firstly, 3 Jhrelth. You have to play 3. No questions asked. This hard to pronounce fucker is arguably the best Tindangle in the deck as it's both a starter AND an extender. If you want a decent turn 1, you need to see him. Jhrelth's Flip effect is really good, letting you either dump or add a Tindangle from deck to hand. Not only does it help load the GY with monsters to bring back with Delaunay faster, but it also gives you a follow up summon/play next turn.
However, the best part of this card is his special set effect, as it's essentially a Foolish Burial for Tindangle cards, not just monsters. This means you can also send Delaunay to GY for set up. Generally though, you'll want to pitch Intruder if he's not in GY to start farming free advantage off him, but if you have another Tindangle already in GY, you can pitch Dholes instead to set up another monster on board.
Basically, he just gets your engine going and does basically everything the deck needs for a starter and extender. The only thing he's really missing is revival, but if he could also do that, then this thing would be cracked. Plus, you can still get revival off by combining it with Dholes, so really, it's not a big deal.
Speaking of Dholes, he's the main extender of the deck. His Flip effect is okay, being able to pitch a Spell/Trap is good since you can pitch Delaunay for mass revival later or Nadel/Euler to search another copy with its GY eff, but actually getting him board is the hard part as he's level 6 and can't revive himself with his own eff sadly. Your best way is getting him out with Angel.
The best part of Dholes is his other two effects, the first of which being a Reborn that special sets when it's pitched to GY. In this deck, you have plenty of chances to send it to GY, mainly Jhrelth, Toddler, and Mail. It lets you recycle the pieces you dump and also procs Intruder in GY, giving you even more advantage.
His other effect is also super strong, as it lets Cerberus attack three times in a turn, but it is once again hindered by the fact he's hard to get on board. However, if you can get him board, always link off for Cerberus, since that triple attack becomes indispensable for finishing off the opponent.
Next is Angel, who is this deck's main way of special setting high level monsters (outside of Intruder) from hand or GY. It's alright and gets the job done, but you need a lot of pieces to make the most of it. Mainly, a monster in hand or GY, which may seem counterintuitive since the deck can easily search and dump, but the best time for this card to proc is the early game, when you lack those resources/use it on other better cards (like Jhrelth).
However, Angel does offer one of the most powerful protection effects in the deck, that being an in built Battle Fader. When it's flipped on the opp's turn, it ends the BP, letting you protect your pieces from being destroyed in battle. One of the biggest weaknesses of Tindangle is losing all their cards early, as it makes it harder to get the advantage payoff, but Angel helps you stabilise.
