The game can automatically construct decks for you based on the cards you have
You can only have 5 cards in your hand at a time, and are unable to draw until you have at least 1 free space in your hand, trap cards can only be set once at a time and are sent to the graveyard after one turn if they don't go off, Monsters can be destroyed in battle by using Elemental RockPaperScissors to bypass attack and defense point differences, some Effect Monsters are Normal Monsters and vice-versa, Fusion Monsters have no Fusion Deck and must be used in the main deck, and you can also fuse compatible monsters to create a new monster that would ordinarily be a Normal Monster
Effect Veiler can be searched by Luciela and recruited by Asteria, so it has better synergy with the White Forest build
In practice, it turns out a beefy creature with a scaling graveyard effect is a pretty sweet deal
For all intents and purposes, Night Express is the maindeck ace of this deck
The case could be made for countless other Angels to be in this spot, thanks to the clever combos and card play they allow, but for sheer force and intimidation, its hard to beat that feeling of getting Akroma, Vision of Ixidor into play
