Defeat ??? or The Lamb for the 1st time, and defeat Satan as IsaacI RULE!

I RULE! is challenge #26. Isaac starts off with Key Piece 1, Key Piece 2, Trinity Shield, Mom's Knife, The Ladder, and The Boomerang. The goal is to defeat Mega Satan. The Boss Room containing ??? or The Lamb does not appear.

Difficulty

With a powerful set of items to start with, this is a rather easy challenge after getting used to Mom's Knife. The most difficult challenge here is, of course, defeating Mega Satan.

Strategy

• Since Isaac will likely be stuck with Mom's Knife as his primary method of attacking, finding powerful items and synergies will prove challenging.
  • Entering any Angel/Devil Room that spawns might yield items that synergize with Mom's Knife (such as Godhead, Holy Light or Brimstone).
  • Though risky, the Boss Rush and Blue Womb will both provide additional chances at good items.
• As a result of beginning the challenge with both Key Pieces, Angel Rooms are much more likely to appear than normal. Due to Angel Room items being generally more useful, it is advised to avoid Devil Rooms altogether.
• It is somewhat easier to beat this challenge with The Polaroid (which doesn't appear after the Mom fight in Afterbirth +) than it is with The Negative, as Isaac is an easier fight than Satan in this challenge. Furthermore, The Chest can provide many chances at useful items that the Dark Room does not.

Notes

• Aside from beating ??? or The Lamb for the first time, the player must also unlock all starter items in the challenge. (Access to Key Pieces, Mom's Knife, etc.)
• Despite being forced to take The Negative, the Cathedral can still be accessed; however, once Isaac is defeated and the chest is entered, the run will simply end and will not count as a completion of the challenge.
• If the player starts the challenge before The Polaroid and The Negative have been unlocked (using I AM ERROR, a sacrifice room, We Need To Go Deeper!, etc.) then the player will need to repeat said method or use another method to advance to Mega Satan.

Reward

• 

  Poker Chip - Complete challenge #26.
