I can understand where that complain comes from: in the past, Expanded has had some degenerate combos, and its not fun to play when, on your first turn of the game, your opponent has already set up a Vileplume (Ancient Origins) preventing you from playing Item cards, or used some combination of cards to make you discard all your hand
Get up to three energy cards and you could deal 40 damage via Special Punch
destroy it, then Special Summon 1 "Crystal Beast Token" with the destroyed monster's original Type, Attribute, Level, and ATK/DEF
Instead, it makes use of a2a-71-arceus-ex as an attacker, dealing up to 130 damage if you have a full bench
Lower Text [End of Attack] By deleting this Digimon, you may play 1 level 4 or lower Digimon card from your trash without paying the cost
Both benefit from proliferation in obvious ways
