Discard a card and sac the token to draw a card
Ethereal Investigator As I mentioned in my Type Four conversations online about including this card in our Type Four stack where investigate cards can be paid immediately, "This is better the more players you have." I mean we run cards like Mulldrifter (which is also free if you evoke it), Cloudblazer, Sphinx of Uthuun, and Sphinx of Enlightenment for card flow from a dork, but if you are running around too many duels, then this is essentially a mana 2/3 flyer that replaces itself and makes 1/1 Spirits with flying on your 2nd card drawn each turn, so one with the Clue after you sac it
This lets you double up on Vampires early, creating a mighty swarm that can easily take out an opponent or two given the number of lord effects and mass buffs the creature type has access to
Bristling Hydra: [Category 2] ETB yield is 3 Energy for 4 mana, then you can spend 3 Energy to place a +1/+1 on this creature and give it end of turn Hexproof
Even worse than Time Spiral, the Jar required no activation cost once it was on the table
A 2/3 flash might also be able to surprise sometimes an opponent and to block a small early creature like Arcbound Prototype or Cabal Initiate
