Heated Heart for Ra is actually an interesting idea, that way I don't have to bait the opponent into summoning a monster in attack position when farming.
I ended up using an Ancient Gear deck with Yusei's mark ability, at first i thought i was having problems, but it turns out i mistook Handsome Dan for Sector Security
I used blue eyes ultimate dragon and destroyed his monsters until he had none left, made the ATK of the fusion monster stronger with blustering wind and yusei’s tie that binds skill and made a direct attack of at least 7000 damage . With trap and glossy cards inbetween & destroying more than 10 monsters and a comeback I had more than 5000 assessment. Depends how strong his deck is too.
honestly just use a deck that's filled with synchro and fusion and activate lots traps and spells, and just destroy monsters. that's what i did and I easily got 6000, without the score boost crystal
