You can get a complete deck with 2 lucky digs in a mini box. This is the definition of a F2P deck. I wonder what somesmuck has in mind as "f2p"? Cyber angels?
P2W deck are decks that necessary need money to be made, like decks using 3 copies of structure deck exclussive cards. P2W deck can also considered decks that require 3 digs in 2+ main boxes, since the amount of gems needed is ridiculus.
Do you find logical a player who just started the game to have to spent 3+ months diging on main boxes to make a decent deck for pvp just to see banlisted/power crept when he finally makes it? Thats why mini boxes and structures exist. To give a chance to new f2p and low budget p2w players to compete veterans. Not a surprise that most miniboxes and sd usually become instant tier decks.
^this is why you invest on staple, not EVERY DECK THAT JUST RELEASED.
Btw master duel also had a same gacha by their trailer, even tho there is feature where you can convert copies to in-game to trade with ( in 40 card format, so it might take a longer time ).
The point? Yugioh official ONLINE platform might be NOT for you. Just play tagforce, or maybe a duel simulator.
