If an artifact or land that becomes a creature this way has been on the battlefield since the beginning of your upkeep (even if it wasn't a creature at the time), it can attack during your turn and its abilities may be activated
From aggressive creatures that can whittle down an opponent's life total to instants capable of countering spells, the types of cards a player chooses to include in their deck has a massive influence on their strategy and how they will try to win a game
This is all about playing slower and more consistently, manipulating opponents, while using Elves to build a board of your own and eventually win
You should sleeve the card with whatever sleeves your library is using, if any
Selecting artifacts that complement your deck and address its specific needs will make your build shine
So having them be effectively silenced allowing you to focus on the game rather then watching profanities scroll by may have in fact been the right call by Wizards of the Coast who notably doesnt have a public forum either for any of their games
