For #6 I am choosing a card that will always have a special history with Rogue Deckbuilder:

This was the card that started it all, the inspiration for the youtube channel, and the catalyst that got me motivated to showcase my “Rogue” decks to the world. I had a TON of fun with this card during the good ole days of RTR and Innistrad blocks. The key card that I used with Epic Experiment was Battle Hymn and regretfully the card wasn’t reprinted for even more shenanigans during RTR / Theros. For nostalgia, here is a playlist of old Epic Experiments:

Unfortunately in THS RTR Standard the only real way to ramp is utilizing either devotion through Nykthos, Shrine to Nyx or Mana Dorks to generate tons of mana. This means lots of permanents and Epic Experiment wants instances and sorceries.

Brewing with this card was a bit of a challenge. I decided to go a Young Pyromancer + Burn strategy to get the most value out of casting a midsized Epic Experiment:
