To give you an idea, for roughly $3.50 a week, you get access to around 300 TIX worth of cards
Quicksilver Elemental technically only has one activated ability, but I figure sometimes well want to copy abilities of a creature our opponent control
At that point, its an easy three-for-one that can totally swing the game in your favor
If an effect instructs you to draw multiple cards, the ability triggers after you draw whichever is the second one for the turn
If you roll more than one die at a time, however, that does count as multiple die rolls
The fact that this card returns as a regular enchantment with the same ability (drawing a card whenever a creature you control deals damage to a foe) is just icing on the glimmering cake
