So, if the mechanic were smoothed out, it would average that: Every 4 Emerging Beasts is a Blessing on each one. So, summoning 4 gets you +12|+12 each time, to a maximum of +120|+120 for 13 cards (total sum of stats among all the creatures). I'm worried since 2 Fractals become insta-kill. 1 Nova is deadly enough.
Point taken
I suggest +2|+2 per 6 creatures
0-5 1|1 (decent for an Other creature)
6-11 3|3 (Horned Frog [2 ] for 2 )
12-17 5|5 (Abomination [5 ] for 2 )
18-23 7|7 (Vanilla Archangel [6 ] for 2 )
I almost wan this to be a Life creature with a casting cost of 1 .
What are the advantages of having an even +2/+2 rate over an uneven rate? (+2/+2, next +3/+3, next +2/+2, random etc.)
This would fit in life well enough, but with your suggested growth stages, and the cost of 1
would probably undermine horned frog. For with one fractal of this, i'd have more frogs for less life quanta.
And whether there is an even growth rate or not, i feel it should end up a bit higher than 7/7. Could be just me, but i feel the above suggestions would be a bit UP
