Until how much trophies does my strategy works?

I am a TH9 in Crystal 1

My usual composed army is:

4 lv6 Giants
4 lv5 WB
192 lv6 Archers

Clan castle : 1 lv5 Golem

Spell: 3 lightning lv5
1 rage lv5
recently i still can do well in achieving 50% in 2400 trophy range, but i am wondering until how much trophy can i keep this strategy.

does anyone else have similar strategy with me?

i got all the way into C2 using only lvl 5 barch so im guessing using your lvl 6 troops (big hairy giants) can go higher.

I went to Crystal 1 with level 4 Barch as th7, you could probably go as far as you want, with enough patience and choosing the right battles to fight.

Add a couple giants and mayb a few wiz for firepower. I would use all heals. Keep them tanks alive and let the archer and wiz clean up. U can probably get close to master league like that
