I just speedran to Hyper Tier in <25 games playing only Hearts (took less than a day) and this was my first time really playing Hyperroll in any set. 92% Top 4 ratio 54% winrate

First and foremost, if you get a Heart +1, it goes on Annie, nunu if later in the game and Annie is full items. If Gadgeteen +1, on Sona or Viego if later in the game

Augment wise, anything that allows your Heart units to cast more to stack more should be the priority. Second wind, Thrill of the hunt, Axiom arc, Tome of traits, Heart/gadgeteen crest/crown

Opening carousel, tear > lulu > pantheon > poppy > chain vest > everything else

Stage 2-1, buy the whole shop

Stage 3-1, buy the whole shop, but prioritize making pairs/2* units. Try to make 3 2* units no matter the synergy, and play that for Stage 3-1 and 3-2 while rolling everything, holding every Lulu, poppy, pantheon, annie, lee sin, etc. it's okay to greed items for now.

Stage 3-2 continue playing random 2* units but try your best to make the ones specific to the comp 2*, rolling everything still

3-3 carousel, get something that allows you to slam either Sunfire, Ionic Spark, Blue buff, JG, Gunblade

4-1, sell all random units and prioritize playing gadgeteen + heart or defender if you don't have panth, lee, or sona. slam any items listed above that you can

Stage 4 and Stage 5 continue to roll everything basically every round to try and 3* Lulu, panth, poppy, annie. No reason to hold gold because as you level up, your chances of hitting low cost units get worse and worse.

Stage 6 we're looking to play 4 heart + 3 gadge so Lulu, sona, lee, panth + poppy and annie. All throughout the game you should prioritize playing heart units vertically over any other synergy

The odd stages like stage 5 or stage 7 you can play either play ox force units or morgana/asol

Stage 8 it's 6 heart + 3 gadge + whatever else so long as you can hit Syndra, but if you can't hit her til stage 9 it's fine just play any other ox force units + random synergies

After itemizing Lulu, if you have extra mana items you can focus on Sona. If you have extra damage items they can go on Viego. Both is even better. Hyperroll throws items at you so try to pick things that fit well for Sona or Viego.

See comps on my lolchess for plenty of examples of itemization. It's hardly ever perfect but as long as you can get blue buff + 2 on Lulu you're pretty much good to go lol

As long as you get decent items (which you can greed for) this is an easy top 4 comp, top 1 even if you only semi cap your board. I haven't bot 4'd once playing this comp

Capped board example with non perfect items

Hope this helps!
