yugioh dragon lord deck trading and collectible card game (TCG/CCG) YGOrganization | CDP: Dragon Ruler

I have a pretty current list for a Thallids build which is essentially an extreme end of this archetype

R Rare Performage Trapeze Magician X LIGHT Rank 4 [ SpellcasterXyzEffect ] ATK 2500 DEF 2000 2 Level 4 Spellcaster-Type monsters You never take damage if the amount is less than or equal to this card's ATK

Notably, white has no cheap interaction (just Gods Willing as a good trick and and Repel the Darkness as a bad trick) and Prey Upon should be a bit better than normal because of how well it synergizes with Heroic

Luckily, they make up for this with their powerful effects and some of the best recovery and healing abilities in the game
