Help Lusamine in Gardevoir deck

[Bantam]

My son (a junior, I help update decks but am not a master in name only) is playing a pretty standard gardevoir deck. We are testing out 2 lusamine (so he can keep pulling one back out), but to make room it took him to 3 sycamore and 2 guzma. Being a junior, he hates to sycamore so that felt safe. However, is dropping to 2 guzma suicide? I’m viewing lusamine as a less effective vs seeker, but I may be off base. Thanks for any advice!

It’s a card that isn’t very good to top deck unless you specifically wanted a stadium from your discard. As such, I would not play it in Gardevoir. The problem is you can’t use the supporter you search for the same turn, which makes this card so slow.
