It does also help if you have strong lineups. The main issue with the modded tournaments is the frequency of the overpowered SR mods, and legendary mods like Toxin and Survival. You get them ALL the time in the modded tournaments and with the big influx of mods, it’s a lot harder to get Nullify, Inspire, Terrify, etc. on your wheel spins. I often have to try 8-10 times to get a single Inspire these days. So I was only willing to risk doing a mod tournament without a stash of mods once I felt I had enough numbers to deal with some losses due to bad mod matchups, and stronger creatures as well that can better handle some of these mods with only commons or rare mods to counter them. Along with a strong DB stash (I try to keep it above 20K at all times).
We got a bunch of modded tournaments when mods first came up but thankfully they do seem to have backed off of the frequency, most players did not really seem to like them very much… not just for what you have to deal with from the AI, but also how SLOWWWWWW modded battles tend to run. Tournaments are already tedious enough for most of us.
