Thanks for the welcome.
Yeah, I am still learning the Chaos Legion and Modern meta to really get a good gauge on what cards are the most often used and etc. And how important some abilities are in them.
For instance, I think magic is very strong in the lower levels (bronze to gold) and Silence is a top tier ability.
And I do like the strategy adjustment you mentioned. I was renting long term, like I just rent every cards for 16 days to go through this season. But perhaps a 5 days rental or something shorter would be more ideal if I expect to suddenly not have as much free time some days. I can un-rent, and then re-rent after I am done to save some DECs. The main factor to me would be how much time I need to do so though. It's a choice between DEC and time.
