This is taken from
pao2's Meren list:
Razaketh, the Foulblooded is another way you can combo off earlier - if you happen to have a reanimation spell without a way to sacrifice a creature, Razaketh can often be a better reanimation target than Protean Hulk , board state depending. With enough creatures or mana out, you can go for Earthcraft + Squirrel Nest immediately and generate a tutor engine bounded only by your life total, but it is far more common for Razaketh to be used as a bridge to the Hulk lines as Hulk lines win immediately. Special thanks to roguelikedev for being the progenitor of the Razaketh/Hulk lines.

Razaketh to Squirrelcraft lines
In the unfortunate situation that Hulk combo pieces have been exiled or are otherwise unavailable, you'll have to go for the Earthcraft / Squirrel Nest combo. The lines are numerous but here are just a few ways to do so with minimal resources. A note that for these lines, if you have extra mana or lands, the requirements get easier since the last few steps of some lines involve fetching 1 drops to untap enchanted lands to generate mana. Again, this is in no way an exhaustive list of all possible Razaketh to Squirrelcraft lines, just some examples. Also noteworthy is that if you do get Squirrelcraft out, Gaea's Cradle will generate infinite .
Life Line, 3 lands

Sacrifice a tapped 1/1 land to Razaketh, the Foulblooded , searching for Squirrel Nest , cast it on your untapped land, proceed to make infinite 1/1 tapped Squirrels and ending with an untapped basic land.
OR, do this set of interactions in case a Null Rod is down or something:
Sacrifice a tapped 1/1 land to Razaketh, the Foulblooded , searching for Utopia Sprawl
Tap your Forest to cast Utopia Sprawl on it, naming choosing black (0 floating, 0 untapped lands)
Tap Razaketh, the Foulblooded to untap your Forest, then tap it for mana ( floating)
Sacrifice a 1/1 land to Razaketh, the Foulblooded , searching for any 1 black drop (you must pay attention to your green mana, as you must end with and an untapped basic land before finding Squirrel Nest ), cast it ( floating)

Tap the creature you just cast via Earthcraft to untap your basic land ( floating)
Sacrifice the 1 drop to Razaketh, the Foulblooded , searching for Squirrel Nest , proceed to make infinite 1/1 tapped Squirrels and ending with an untapped basic land.
In either case:
If you have 2 more life to spare, sacrifice a Squirrel to Razaketh, the Foulblooded to find Plunge into Darkness , tap your basic to cast it to gain infinite life. You may now tutor as many cards as you want from your deck.

Manaless Earthcraft Line, 5 lands (N/A for this deck)
You can also begin this line with Razaketh, the Foulblooded , 2 other creatures in play, 5 lands one of which must be basic, and >16 life (>18 life for infinite life with Plunge into Darkness ).
In this case you will need to tutor Mana Crypt with that extra creature to complete the same chain outlined above. If you are unable to do so, you'll need to >18 life (>20 for infinite life with Plunge into Darkness ) and instead tutor for Chrome Mox or Mox Diamond first depending on your hand and casting it, tapping that for G, sacrificing the second creature to find Life / Death , the continue with the above line. It will require 2 extra life compared to the Mana Crypt line since you'll need to tutor another 1-drop to get the requisite mana.
