As a new player, I have added my cards to this website and I want to make decks from them, but there doesn't seem to be any even remotely convenient way to pick cards for my decks from my collection.

-No quick way to add cards via drag-and-drop, right click, or even just a button next to them.
-Cannot add cards to my deck AT ALL while in image mode (I don't know what the cards do without seeing them).
-Cannot add multiple copies at the same time, have to laboriously select cards from the list and find "add to deck" from the dropdown menu, which only adds 1 of each.
-Only 30 cards listed per page, and selection doesn't carry over between pages, adding even more clicks.
-Cannot increase or decrease number of copies even in the deckbuilder menu while in card image mode, despite the number of copies being displayed.

This is the fourth deck builder/collection manager website I have tried and so far the best one, but the UI is still just absolutely abhorrent. All these sites seem to expect me to just know every card by heart and add them via typing their names in a box. It's extremely unfriendly to new players.

Is there something I'm missing? Or any alternative website with better UI?
