it took me a little while to realize,
but this card allows exponential growth.
after the initial delay, you get:
turn | temples | knights |
1 | 1 | 0 |
2 | 2 | 1 |
3 | 3 | 3 |
4 | 4 | 6 |
5 | 5 | 10 |
6 | 6 | 15 |
7 | 7 | 21 |
8 | 8 | 28 |
9 | 9 | 36 |
10 | 10 | 45 |
11 | 11 | 55 |
this does, of course, flood your creature and permanent slots.
also, the damage is very low; a single shield blocks it all.
It does, however, allow a chimera, and continue spamming creatures after that (otherwise only avaible via fractal).
Seeing the mob cap, the time required to grow, and the high cost,
I'd totally remove the delay from the map, and/or give the knight better stats.
