Its a bit of both, to be honest.
Its a state of costless play where you can use a single level 4 monster like a boss.
The example that caused this semi-rant was when I played against Bujin Yamato.
My opponent literally only used this single Level 4 for the entire MATCH.
Not just one duel, the whole match.

Granted Im not the worlds best player, but it shouldnt be too hard to run over a single 1800 ATK Level 4 monster
whos effect on its own doesnt do much but fill the grave.
That effect, in the old days would be a cost for getting another monster to your hand.
In reality, what its really doing is just loading Yamatos effect revolver with bullets, effectively giving him any effect hed ever need.
Yeah, of course you win when you can hand pick effect from the graveyard to fit any situation in a virtually costless manner.

And the sad part is this isnt even the most degenerate thing in the game.

I know why it USED to have effect costs.
You had to give up something to get something, it was literally a cost.
Your better cards required more of a sacrifice.

Costs now are not costs, and thats a problem.
Everything thats disguised as a cost is really a benefit.
An effect requires you discard to the Graveyard?
No problems, this archetype exclusively uses graveyard effects
Spending Lifepoints?
Well gain more back than you spent
This card tells me that everything I lost to gain an advantage in this duel is going to come back again after I already used it

sigh
Thats what makes this game really degenerate.
Theres is no actual penalty for using a long chain of cards and efffects.
Every archetype has a built in recovery for its own weakness.
