So this is a project I wanted to engage in- To make a set of 10+ super-budget 60-card decks that are simple, relatively easy to play, relatively easy to understand, and bring across the fundamentals of how Magic Works. We've since gone way past 10, with tons more in the works, and I've really enjoyed the challenge of trying to make these decks easy to play and understand, fun, and all under a $15 budget, sideboard included.
The main goal here is that you could easily build these deck for a low cost and use them as an easy introduction to how magic works, to teach a group of new players both how to play, and give them a sense of Why, a sense of what fun things they're getting into. These decks aren't gonna be particularly good, or even legal in any particular format if it stops me from including a card I think is good for the deck, but they should be fun and interesting without being too hard to get into. They should be an easily-accessible example of how fun Magic: The Gathering can be.
This is one of the more advanced decks- Not really the first decks you want people learning with, but a sweet, budget deck you can use once new players are already on their feet to really knock their socks off and get them to think about something you can do in Magic that they might not have otherwise realized.
So first I was going to try and make an actual Goblin Aggro deck, but then I decided I'd make something funnier instead. Thus- Goblin Grenade Combo. It's an advanced lesson mainly because getting combo-blasted for 15 out of nowhere seems like a bad way to learn your first game, but a hilarious thing to learn is possible in your 6th or 7th game, maybe.
As for budget: Maindeck cost is currently at ~$12 (according to the middle blue numbers on this very site under estimated value), sideboard at about ~$2.50, sneaking in under my $15 budget.
So mostly this section is going to be notes on why I think these are good cards to learn from:
Your goblin spam is basic and cheap- Glory-Chaser will occasionally become a 2/2 menace, which is nifty, Arsonist hurts if they block it or not, and Rigging Runner will often enter as a 2/2 first strike. Dragon Fodder and Krenko's Command let you spam 1/1s, and Hordeling Outburst is a little slow, but does the same.
All of these cheap and expendable Goblins are fuel for Collateral Damage, Goblin Grenade, and Barrage of Expendables, all of which let you send those 1/1 tokens face for respectable damage.
For your combo cards, Quest for the Pure Flame will double your damage for a kill turn, or Howl of the Horde can be used to turn (ideally) a Goblin Grenade, or, if you have to, a Collateral Damage into a triple-cast nightmare of a spell that just nukes your opponents into oblivion.
....Aaand I guess that's the deck. You Go Face, that's about all there is to it.
Hey, would you look at that. I don't have to make excuses about the Mana base this time.
As for the sideboard, this IS supposed to be a sideboard they learn how to use, to make their deck perform better in the right matchups, or just in general to customize their decks within constraints.
I had a lot of trouble coming up with a sideboard for this linear of a deck, but I decided on a few more goblin options, like letting you use Emberwild Augur, some shatters that probably aren't worth boarding in almost ever, when you can just go face instead, and a full package of shock and searing spear. If anyone has suggestions for good sideboard/matchup-dependent options that are cheap enough, I'm all ears, throw 'em in the comments.
Edit: Oh hey, Dragon's claw is only 25 cents. Perfect, in she goes. Further suggestions still welcome.
