Well, as an eclectic and grey-haired wizard I have a few nuggets of wisdom to share I suppose
Hosting a tournament with friends using the old cards can be a rewarding bonding experience with a hint of nostalgia
for one thing, one of the piles had most of the energy
However, the Energy-to-Damage ratio between the two makes it incredibly strong in the first few turns of the game
Rather than forcing players to play around a continuous effect, limiting plays to a single attribute or monster type, Evenly Matched is activated at the end of the Battle Phase and forces your opponent to banish cards of their choice until both players control the same amount of cards
Im obviously keen to keep an eye on 151, to see if something special can happen there too (like Crown Zenith, its a special set with no booster boxes), but my hopes arent high
