MtG has large fluctuations in how much each card can be worth
It even mills cards itself to grow, though I wouldnt recommend relying on it as your only source of mill
So, if you're adding three +1/+1 counters to a creature, and High Score is on the battlefield, you'll instead add four +1/+1 counters
These cards can then be cast, for any color of mana, once Haldan joins him in play
Just dont expect this trend to be too extreme: Magic 2015s cards rebounded from their rotational lows at a quicker rate than comparable cards from Journey to Nyx , for example, but both sets contain the same number of $5+ cards today
I hope so because there has been a massive trend in the Magic economy that many players may be overlooking
