I mentioned the [scryfall]Crater Elemental[/scryfall] + [scryfall]Alesha, Who Smiles at Death[/scryfall] interaction previously. Why not try and bring that into constructed? Probably, because it won’t work the way you want it to, but we can try…

What do we need here? Hard to say. Its basically a list of just a bunch of interactions with different cards, that hopefully work together. Very little removal, so this isn’t actually going to do anything in standard, but there’s some nice interactions here.

[deck]
[creatures]
4 Crater Elemental

3 Goblin Rabblemaster

1 Gurmag Angler
[/creatures]
[spells]
4 Rakshasa’s Secret
4 Thoughtseize
4 Kolaghan’s Command
1 Foul Renewal
1 Palace Siege
[/spells]
[lands]
4 Bloodstained Mire
2 Polluted Delta
2 Wooded Foothills
4 Temple of Malice
4 Bloodfell Caves
4 Mountain
5 Swamp

[scryfall]Goblin Rabblemaster[/scryfall] can win on its own in the right circumstances (although right now people are prepared for it), but it can also produce fodder for [scryfall]Tymaret, the Murder King[/scryfall] and [scryfall]Sidisi, Undead Vizier[/scryfall].

Discard spells are a good way to get stuff into your graveyard for delve (although I don’t have that much delve here), but with some luck, [scryfall]Rakshasa’s Secret[/scryfall] can put some value into your graveyard (like [scryfall]Bloodsoaked Champion[/scryfall]).

[scryfall]Foul Renewal[/scryfall] should be pretty good with [scryfall]Crater Elemental[/scryfall].

Plenty of stuff happening here.
