Notes & Combos
I really liked the synergy of Hapi with hand traps and Horus cards in general with needle ceiling, so I made this somewhat silly deck. Because Horus cards are frequently more annoying for your opponent than the extra deck monsters you could make with them, you're able to run ultimate slayer with no problem. Clear wing synchro dragon also does a great job of covering the weaknesses of the Horus cards and is an easy way to get rid of mystical elf.
On turn 1, you typically want to lay down horus bodies and hope for the best. Ideally, your opponent invests more energy in clearing your monsters than you put into getting them on the board. In this meta, people arent usually expecting needle ceiling or drowning mirror force, so it's easy to punish people who push past your monsters.
On turn 2, you arent usually going for an OTK. Instead, you want to use the excellent card economy that Horus provides to let your opponent overextend. PEP is often a solid play once they are low on cards.
The entire extra deck is situational; Horus bodies are usually better.
