This is an aggressive midrange deck for casual multiplayer with some friends and I have no idea what I'm doing! Any feedback or suggestions are welcome.
The goal is to gain card advantage, copy spells, and overwhelm people with low cost tokens. Lucky Clover is the cheapest option for copying cards, but we're limited to 4 of them. To get around this problem, many of the adventure cards generate tokens or give counters to take advantage of Doubling Season. With both cards down, you can swarm the field with tokens. Chandra, Torch of Defiance acts as another win condition if you cast her with doubling season out.
Quite a few of the cards in this deck are adventures which provide you with two options for what you can cast. It's typically best to use the adventure side first so you can take advantage of any lucky clovers you have. When you cast the exiled card later, Pia Nalaar, Consul of Revival can produce thopter tokens. One thing to keep in mind is that you might not always want to immediately play Pia because she needs to be defended. It's nice to have some cards in exile before she goes down.
Showdown of the Skalds or Questing Druid with a lucky clover down help ensure that you always have cards to play. You can typically cast one on turn 4 or 5. Everything in the deck can be played for 5 mana or less, which means you should be able to use 2, 3, or even 4 of those exiled cards on your next turn. One thing to keep in mind with showdown of the skalds is that it uses lore counters and doubling season will affect the card when it enters the battlefield. If Pia is down, you get thopters for every card you can play. Chandra provides you with more mana or another way to exile cards if it's needed.
For this deck, I believe 23 or maybe even 24 lands might be considered optimal. But I'm using 22 lands to try and prevent a bit of mana flooding when you are exiling 4 cards off of showdown of the skalds. Personally, I want to exile 4 cards and play all 4 of them on the next turn. Getting 2 or 3 lands means I can't do this.
I've tried using 4 showdown of the skalds and 4 questing druid, but I feel like 3 of each may be better for similar reasons. When I cast either one of them, I don't want to see those two cards in what gets exiled. It's not a bad thing if they appear, but I want to exile a bunch of cards one turn, play the adventure side the next turn, play the non-adventure side the turn after, and repeat this cycle. Edgewall Innkeeper draws cards as adventures spells come down to help make this happen.
I've tested the deck in Historic on MTG Arena by swapping out the cards in the sideboard for their equivalents in the main deck and Reflecting Pool for a basic land. It seems to struggle a bit against aggressive decks like elves or merfolk. There's a point where they can swarm the field early on and get their creatures up to 3/3.
This is over the kill range for one copy of Bonecrusher Giant and under the power required for Giant Killer to work. Being able to wipe the field when they start running out of cards to play helps, but there's only one copy of Realm-Cloaked Giant. Copying tokens with Lovestruck Beast helps to buy time, but it can be hard to gain an advantage in a match like this and I'm not sure what I could change to make this easier.
A couple things to note are that because we are copying cards and exiling them, this deck is more resistant to counter spells and discard effects. Counter spells would only affect one copy of our spells and discard effects can't target any of the exiled cards you can play. This deck is also able to recover relatively quickly from a board wipe with all the ways it can generate tokens.
When all of the adventures except Horn of Valhalla are factored in, the converted mana cost is 2.60 and it looks like this - https://imgur.com/a/dBjyq7J
