Meaning Black Hole can consistently be gotten off before Sanctuary can be consistently be gotten off, because of the randomness that rainbow decks have.
And it didn't get flawed when I brought the nymph into question, because it's the same issue.
You're going to have to stop with the small messages if we want to create any argument. Again, what you said has already been pointed out in
another thread, much more extensively than this and covering many other points that you are making. It also has been already shot down.BH isn't used so often, the only increased occurance of it being due to SoFo (which is also a different problem as a whole.) As omegareaper7 has pointed out, the randomness that rainbow decks have is only limited to quanta pool IF your rainbow deck is a quantum tower powered deck, which is not the case (Most rainbows are speed rainbows, most rainbows have supernova, supernova does not randomize quanta pool. Figure out the result.) If you mean draw randomness, then the Gravity Deck with the Black Hole card also has it.
And yes, it did get flawed. Black Hole is Black Hole, Amber Nymph is Amber Nymph. Black Hole is a spell and therefore cannot be stopped through conventional means (only through sanctuary), and Amber Nymph is a creature that can be dealt with in several other forms (Examples being Fire Shield, Skull Shield, Procrastination, Reverse Time, Fire Bolt, Ice Bolt, Lightning, Freeze, Devour, Shockwave, Drain Life, Guard...). Black Hole also has a cost, while the nymph has double (or in the upgraded case, triple) the cost; also, the Nymph has a summoning sickness, which means not only will it be summoned late during the game, which makes the BH effect less useful (Supernova bows will have drained most parts of their quanta and if they are smart they will have only been playing what is necessary, therefore cutting down on the effect of BH and having already tons of creatures in the field if built properly), and that it will also have no effect other than a simple 1 damage on the turn it is cast due to the summoning sickness, leaving the opponent open to kill it / make it useless in that one turn of breather he has.
