Before Syr Gwyn, Mardu Knights never had a proper lord, and now since they do, I felt that giving Syr Gwyn a warm welcome through the inclusion of cards like Adriana, Captain of the Guard, Mrton Stromgald, and Haakon, Stromgald Scourge made a lot of sense
Collectors Vault, Matzalantli, the Great Door, and Currency Converter, which is an all-star in my Karador Cycling deck, all allow us to draw and discard a card plus a little extra value
Each time I mentioned something like this, though, I was met with acknowledgement and agreement, which hopefully contextualizes that this was an early alpha build
The only downside to Blast Burn is that you have to flip a coin every time you use the move and if it's heads you have to discard 2 energy cards from Charizard, if it's tails you have to discard all 4 energy cards
You also need to make sure you hit your land drops, either with draw effects (Qiqirn Merchant and Adventurers Airship provide usable bodies as well as draw smoothing) or cards that directly give you lands or mana (World Map, landcyclers, Blitzball)
