in order to be successful in both PvE and PvP, you need to go rainbow
This is a grossly false statement.
I have mono

decks that are all quite effective at PvP and PvE. This is in addition to the standard fare of mono
, mono

Pretty much every one of my decks, PvP or PvE, is a mono deck with a few duo's thrown in there for good measure. I only use a rainbow for fg farming, and I only have about 400 fg wins out of ~ 9200 total.
You can be plenty successful in this game without ever using a rainbow deck, you just have to open up your thinking and be creative.
To get back on topic, all the mono and duo decks I use would barely be phased by a black hole. A life rush will beat a black hole deck every time as black hole is essentially a wasted card in this case. Black hole is strong against rainbows, but that is by design. If you are scared of black hole, switch to a mono deck.
