tcgplayer ikoria booster box Lair of Behemoths Collector In so doing Ikoria: Lair of Behemoths Booster

I used to have a deck like it on Dueling Network but never wrote down or recorded the composition before it was shut down

And then on top of that, once per turn you can pay 500 life points to pretty much use this guy as its own fusion spell: allowing you to fusion summon a Frightfur monster from your extra deck using cards from your hand/field as the materials

The cards secondary effect is that whenever you cast an instant or sorcery spell while its on the battlefield, it gets a +1/+1 counter, to become at least a 3/3 attacker or defender

Substitoad This card is one of a few OTK/FTK strategies that uses the top card further on this list But this one famously won a Yu-Gi-Oh
