The medal count is FINE, it's your ability to find them that's the problem.

Give you a hint. JUST hit L9 valleys for medals.

Send 11k Archers, 350 Ballista, 1 pike, sword, warrior.

DO 9 waves of that spaced 10-15 secs apart so you can abandon it.

Do that twice, if no medal try again tomorrow.

HINT:

Rose: L9 Lake/Grass
Lion: L9 Desert

Rest find out yourselves.
