I noticed a few things while actually playing, so I would like to try various things and add more updates in the future
In Legacy, decks need to establish a commanding presence right out of the gate
Darkrai ex Deluxe Pack: ex #378 Card Type Pokmon Element Darkness Stage Basic HP 140 Weakness Grass Retreat Cost 2 Evolves From - Pokmon Darkrai Artist Nightmare Aura Whenever you attach a [D] Energy from your Energy Zone to this Pokmon, do 20 damage to your opponent's Active Pokmon
Trainer Blue is a hail Mary lifesaver, reducing all incoming attacks on the next turn by 10, while Trainer Leaf is the tactic-changing option to reduce the retreat cost for that turn by two
If the luck of the draw lands such that you can get two copies of Lucario on your bench, all of your fighting-type cards will deal an additional 40 damage per attack
Because of my hypothetical ten turns to mill everyone out, wed need to be around thirteen cards from every other players deck from turn three onward
