Bruvac the Grandiloquent + Traumatize

Overview
Traumatize tells the target player to mill half their library, rounded down. Because Traumatize uses the word “mills,” Bruvac the Grandiloquent’s replacement effect applies and doubles the number of cards milled, so the target mills twice floor(L/2) cards (where L is the number of cards in their library). For even L that equals L (the whole library); for odd L it equals L−1 (leaving one card). Bruvac applies here because Traumatize literally uses the word “mills” (Ruling [2020-06-23]) and milling multiple cards this way is treated as a single “happening” that a replacement effect like Bruvac can modify .
Step 1
Determine the number of cards in the target player’s library at the moment Traumatize would resolve; call that number L.
Step 2
Traumatize’s instruction is to mill half the library, rounded down, so compute N = floor(L/2).
Step 3
Because Traumatize uses the word “mills,” Bruvac’s static replacement effect applies to that milling event and replaces it so the player mills 2×N cards instead of N (see Ruling [2020-06-23] and consider the milling as a single happening a replacement effect can modify under ).
Step 4
If 2×N is greater than the number of cards remaining in the player’s library, they simply mill all remaining cards (you can’t put more cards into the graveyard than exist in the library).
Step 5
When putting those cards into the graveyard as they are milled, the player may choose the order in which the cards go into their graveyard (Ruling [2004-10-04]).
Step 6
If the library is emptied and that player later attempts to draw a card, they would lose the game for attempting to draw from an empty library .
Resolution
When Traumatize resolves, compute N = floor(L/2). Bruvac’s replacement effect makes the player mill 2×N cards instead of N. If that equals or exceeds the number of cards in the library, the player mills all remaining cards. The player may put the milled cards into their graveyard in any order they choose (Ruling [2004-10-04]). If the library is left empty and that player later attempts to draw a card, they would lose the game for attempting to draw from an empty library .
