Those big wurms will be very happy to get copied by Rhys' second ability, so this deck could really get out of hand if left alone for long enough
That said, people shouldn't be concerned with the "math" part, as this deck can be incredibly simple
Monsters show up on the battlefield when cast, but the micro-cutouts arent very impressive
Food Chain is a three-mana enchantment that, generally, threatens to win the game immediately
Adding "DARK Normal" to this makes this card nigh-impossible to Summon, and in comparison, Neo-GEPD is easier at "3 Level 8 monsters"
Like the Booster packs, you are not guaranteed to pull a Base 1999-2000 Holographic Machamp from the U.K variant, I have opened some with and some without it, the remaining cards will have the 1999-2000 copyright change
