Q&A Rulings
- Q: When Fusion Summoning a "Red-Eyes Slash Dragon" with the effect of "Red-Eyes Fusion", can I use "King of the Swamp" and "Gearfried the Red-Eyes Iron Knight" as materials?
- A: When performing a Fusion Summon with the effect of "Red-Eyes Fusion", you must always include a "Red-Eyes" monster listed as a material on the Fusion Monster. Since the materials for "Red-Eyes Slash Dragon" are "Red-Eyes B. Dragon" and 1 Warrior monster, you cannot use "Gearfried the Red-Eyes Iron Knight" as the Warrior monster in combination with "King of the Swamp" that is applying its effect.[1][2]
