This two-mana creature has shroud, making it nigh untouchable to your opponents, and anytime you cast an enchantment spell, you draw a card
(1) If this card is Special Summoned: You can Special Summon 1 "Elemental HERO" monster from your Deck, then if your opponent controls a card, you can inflict 400 damage to them for each, also you cannot Special Summon from the Extra Deck for the rest of this turn, except "HERO" monsters
In fact, a lot of removal spells are bad against this build except specifically when it comes to interacting with your combo, such that there will be awkward tension for opponents when trying to sideboard against you
Two turns later, they stop, spells keep flying, and Sentinel starts refilling your hand
As long as you target your legends, the casting and equip costs are equal to the famous Swiftfoot Boots, even if the ward is less stellar than hexproof
