50 to WHAT? It's 50 or go home. Consistency's sake. It's the reason why all top-tier Yugioh decks are 40 exactly, even though you can go up to 60.

You say "percentages" but you don't even give any ratios. Monsters should take up about 40-60% of your deck. There are exception decks but they work off a gimmick and not off consistency.

Your "N3" is something called a winning image. It's kinda necessary in every deck.
