Echelon of the Fire Kings Card Text Special Summon 3 FIRE monsters (1 Beast, 1 Beast-Warrior, 1 Winged Beast), 1 each from your hand, Deck, and GY, but their effects are negated, also destroy them during the End Phase
This effect isn't what makes it so good, rather it's the effect that adds any "Red-Eyes" card from the deck to a hand when sent from the field to the Graveyard
You can scale up other Fire-type attackers very quickly with this, and do plenty of damage before the opposing trainer is even done setting up
Its first use allows you to target a face-down Spell or Trap and destroy it
What does each card do, are they any good, and how do they stack up to similar cards
A very underrated card for sure but I would avoid playing it these days without card filter or discard outlets
