..and another thing: how the hell all this could do *any* harm to PvP?!
Very simple.
Say, i have more nymphs than you, because i offer babies to the oracle every day. I now have a bigger choice of decks versus you, simply because i have luck spinning the wheel. The decks do not need to be OP to give me an advantage, they just need to not be UP. They can also work as strong additions in existent decks. Take monolight, popular BL deck. When i add white nymphs, i gain :
- A stable, CC resistant creature that hits hard
- With an ability that gives me HP (good for a stall, which monolight is)
- With an ability that gives me more quantum generation (as if solar shield wasn't enough to bodyslam denial)
A player without those has a weaker monolight. Hence, is at a disadvantage. And that's just modding, making new decks using those gives you an advantage through more options (versatility), based on luck, and less importantly, veteranship.
