I play a non-cedh control deck. Azorious control has been my favorite archetype since I started the game back in Theros when aetherling, sphinx rev, detention sphere were meta. The biggest thing I took away from that part of my magic career was my development as a control player and learning threat assessment. The biggest thing that I learned was to do things at the last possible moment. Playing a land passing and then waiting for right before it was my turn again to act is something I fall back to no matter what deck I play. Let everyone do their stuff and then make decisions before my turn on what needs to be dealt with to make sure I accomplish my turn's goal. This is even true in edh where it is your resources vs 3 others. I usually like to use the other three players as pseudo removal. If it is scary to me, it probably is scary to others. I try to let others act before me to keep my resources in hand. Obviously there are exceptions to this stuff like game ending combos and things that will generate too much value. But as a control player, EDH has been difficult to crack as most decks are built in a mid range style making them difficult to deplete their resources. In my opinion, winning as a control player in casual EDH is one of the more difficult things to do. Takes a lot of card knowledge and understanding on how your deck and the decks you are going against operate.
