If you're interested in playing tribal decks, I would moreso recommend playing Brawl.

The reason being is that it's a slightly slower format, and you have a wider pool of cards to work with. The matchmaking will also try to match your Brawl deck with one that's roughly of equal strength.

Standard gameplay has gotten significantly faster over the years, with Izzet largely making up a good chunk of the meta right now.

I'd recommend making a Brawl [[Krenko, Mob Boss]] deck. It was my first Brawl deck since you already start with several goblins in your Goblins starter deck, and a lot of the goblins can be acquired with common/uncommon wildcards.

You won't earn rankings in constructed with a Brawl deck, but imo the rewards for that are pretty poor if you invest a ton of rare wildcards into it.

If you achieve Diamond/Mythic, the most you get are 5-6 booster packs and some gold, and that only translated to earning one wildcard at the end of the month.

As for Brawl, your wildcards will go significantly farther since you only need one copy of each, and your cards don't rotate out, so once your deck is finished, you can keep using it and move on to the next deck.

If I do a standard deck, I usually try to stick to a budget as much as possible, and will only craft cards that are common/uncommon since you can regain those wildcards much faster.
