• G/W Tokens (RTR, Theros)
• B/R Aggro (RTR, Theros)
• B/G Constellation (Theros, M15, KTK)
• Mono-Green Aggro (Kaladesh, Amonkhet, Ixalan)

I've ran the following EDH decks before. Build order is in descending order:

• Oloro, Ageless Ascetic - Pillowfort, bought the precon and disassembled in 2014.
• Trostani, Selesnya's Voice - Tokens, built and disassembled in 2014.
• Chorus of the Conclave - +1/+1 Counters, built 2016 and disassembled in 2016.
• Selvala, Explorer Returned - Evolved from my Chorus list. +1/+1 Counters, built and disassembled in 2016.
• Atraxa, Praetors' Voice - Evolved from my Selvala list. +1/+1 Counters, built in 2016, disassembled in 2017.
• Ruric Thar, the Unbowed - Big Creature Stompy, built and disassembled in 2017.
• Kruphix, God of Horizons - Control, built and disassembled in 2017.
• Prossh, Skyraider of Kher *f-etch* - Food Chain, built and disassembled in 2017.
• Brimaz, King of Oreskos - Tribal Soldier, built in 2017, disassembled in 2019, reassembled in and disassembled in 2021. Evolved into Adeline, Resplendent Cathar.
• Karametra, God of Harvests *f-etch* - ETB Combo, built in 2017 and disassembled in 2019, reassembled and disassembled in 2021.
• Sigarda, Host of Herons - Enchantment Pillowfort, built in 2018 and disassembled in 2019.
• Siona, Captain of the Pyleas - Evolved from my Sigarda list. Enchantment Combo, built and disassembled in 2021.
• Yasharn, Implacable Earth - Evolved from my Siona list. Enchantment Prison, built and disassembled in 2021.
• Lyra Dawnbringer - Tribal Angel, built and disassembled in 2021.
• Zo-Zu the Punisher - Land Hate, built April 2021 and disassembled April 2022.
• Celestial Kirin - Built December 2021. This was built as a budget deck with a max budget of $50. The budget has since been raised to $100 in March 2022. Disassembled in December 2022.
• Kaalia of the Vast - Built May 2022 as a prison/stax deck that breaks parity by using Kaalia's ability to cheat creatures into play. Disassembled July 2023.
• Jhoira, Weatherlight Captain - Built in Summer 2018 as an artifact-based combo deck, disassembled in 2019, and reassembled in April 2022 as an artifact-based storm deck. Disassembled in July 2023.
• Selvala, Heart of the Wilds - Built sometime in early 2017; Evolved from my Ruric Thar, the Unbowed deck. This was my cEDH deck, as a ran a slightly modified version of the Brostorm list. Rebuilt and modified a bunch during 2020, 2021, and 2022. Finally disassembled for good in 2023.
• Sythis, Harvest's Hand - Built in June 2021 as an enchantment-based prison deck. I'm really proud of the deck and it's probably the deck I've put the most amount of work into tweaking. However, after a while people just refused to play with me if I used it because people don't like prison and it sucks. Disassembled in May 2024 because I never play it anymore.
• Oona, Queen of the Fae - Built in November 2021 as a combo deck, revamped in fall 2022 as a tribal faerie combo deck. I loved this deck, but the deck felt like it wanted to do three different things and couldn't decide what it really wanted to do. It felt like it lacked direction, and instead of trying to fix it I opted to disassemble it. Disassembled in May of 2024.
• Giada, Font of Hope - Built in June 2024. Angels are my favorite tribe in Magic and I really wanted to build a tribal Angel deck, so I did. However, I kind of hated how it played and I don't like having multiple decks of a mono-color, and seeing as I already had Adeline, Resplendent Cathar and enjoy playing her more, I decided to disassemble Giada, Font of Hope in favor of making my Adeline, Resplendent Cathar deck better. Disassembled in October 2024.

• Mono-Green Stompy

• Cormela, Glamour Thief
• Kaalia of the Vast
• Winota, Joiner of ForcesGC

I'm currently running these EDH decks in order of oldest to newest:

• Titania, Protector of Argoth - Built in 2017, disassembled in 2019, remade in 2022. I used to run a lands-matter goodstuff list, but I wanted it to remake it and be better, so I remade it into a lands-based combo deck.
• Adeline, Resplendent Cathar - Built in 2021, disassembled in 2022, reassembled in 2023. Evolved from my Brimaz, King of Oreskos deck. It's a very fast and aggressive combat-based deck that seeks to quickly overwhelm my opponents with tokens and anthems.
• Cormela, Glamour Thief - Built June/July 2024. Cormela is one of the legendary creatures in Magic I most wanted to build around because for a long time I've wanted to build a Grixis instant/sorcery-based storm deck, but haven't found the chance. I ended up building her as a $50 budget deck for my playgroup's budget deck challenge.
