2 Aether Swooper and 2 Era of Innovation moved to Sideboard
+2 Glint-Nest Crane and Blink of an Eye
+1 Prophetic Prism added to Main Deck from Sideboard
+2 Implement of Combustion
This new iteration of the deck has given the deck the last bit of fine-tuning to be good and added a sideboard to deal with threats that are specific to other decks.
Main Deck
Aether Swooper and Era of Innovation was moved from the main deck to the sideboard to keep the combo around, but it's less useful than it's proven to be
The second Prophetic Prism added from main deck as well as Blink of an Eye for draw power. The latter also grants control for non-land permanents such as Seal Away and also disrupts Planeswalkers.
Glint-Nest Crane is not as effective as it could be, but it's a 2-drop with higher toughness and flying than Aether Swooper and lets you add more cards from your hand. Get a free scoop up on your artifact of choice if you need one and also keeps some cards safe from mill decks
Speaking of draw power, adding 2 more Implement of Combustions for more damage and draw power as 1 drops
And now for Sidedeck tech:
Incendiary Combustion and Star of Extinction deal with token swarm decks such as Vampires and Saprolings.
Commit/Memory is your anti-mill/control tool. Wait for them to tap out and then cast Memory to reverse all of your oppnent's work in one swoop
Fireforger's Puzzleknot is another damage option. If you use this, Era of Innovation and Aether Swooper can also be used due to having more cheap artifacts to drop in
Captain Lannery Storm is a 3 drop with haste that adds a treasure for Fireweaver procs and forcing your opponent to move against it
The Antiquities War is basically another Glint-Nest Crane with the potential for turning your artifacts into 5/5 beatsticks for a turn. Only use this as a last resort, especially for your Panharmonicons as they're key to your damage combos
An extra Fight With Fire and 2 extra Blink of an Eye just in case
