Start by accepting that your deck won't be as straight-up competitive as it could be with Mox Opal — it's a staple, and cutting staples, especially for budget reasons, inevitably involves giving away some percentage points here or there. Maybe you can gain some improvements in unusual matchups, though.
What does Mox Opal do for you?
Consider what ...
From the Comprehensive Rules:
711.12. When a double-faced permanent transforms, it doesn’t become a new object. Any effects that applied to that permanent will continue
to apply to it after it transforms. Example: An effect gives Village
Ironsmith (the front face of a double-faced card) +2/+2 until end of
turn and then Village Ironsmith ...
Yes, you can do this.
Street Wraith has the ability
Cycling—Pay 2 life.
which (as the reminder text states) is shorthand702.28a for
Pay 2 life, Discard this card: Draw a card.
Since this is an activated ability, everything to the left of the colon (:) character is the cost that must be paid to use the ability.602.1a You pay the cost (discard the ...
A transformed creature is the same creature it was before. Auras don't fall off and temporary effects don't go away.
Now, "exile and return transformed" cards leave play, so they will enter as new objects.
You can copy the triggered ability with Strionic Resonator, but after the copy resolves, the original won't do anything.
Booby Trap's triggered ability is
When the chosen player draws a card with the chosen name, sacrifice Booby Trap. If you do, Booby Trap deals 10 damage to that player.
If the ability is on the stack and you copy it with Strionic ...
The primary threat to the Mindslaver player is a free instant that cannot be wasted. The simplest example is if the opponent starts out with no cards in hand, and then draws Temporal Mastery followed by Force of Will, and they have fewer than 12 lands. The Mindslaver player cannot afford to give the opponent an extra turn outside of the lock, and they can't ...
You have to choose and return a valid target if there is one.
You have to follow instructions of all spells and abilities that resolve. Scrap Trawler's ability requires you to target a valid card in your graveyard if possible, and you have to return that card to your hand if it's still a legal target by the time the ability resolves.
In the general case, ...

Sad to say, you can't build a competitive Affinity deck without Mox Opal. Mox Opal is expensive for a reason - it's freakin' powerful, so powerful it's been in numerous what-card-should-be-banned-from-Modern discussions.
Hall of Famer and noted Affinity expert Frank Karsten once wrote an article discussing how Affinity could cope if one of its key pieces ...
Based on testing, here are the strategies that worked for me, specific to the Gifts reanimator deck.
Attack their mana base
As Rahzark mentioned, the green Tron deck's greatest weakness is the UrzaTron combo itself. Forcing Tron to play with lands that tap for 1 mana each turns it into a deck that can barely ever cast anything relevant. With the massive ...
Your friend is not correct. As you identify, Doubling Season's second ability only cares about counters being placed on permanents you control.
If your opponent put a -1/-1 counter on a permanent you control, Doubling Season applies and two -1/-1 counters are placed instead.
Quillspike's ability cost doesn't place counters on permanents. It removes them. ...
The answer really is to go fast. I say this as a long time UR player in Modern. By go fast, I mean you want to pressure your opponent's life total and build big creatures.
It looks like you have Master of Etherium in the main. That's a great card for you because it can often push your creatures out of Pyroclasm or Anger of the Gods range. UR decks are ...
