Look at it this way.
Grind PvP with the same old decks playing people with likely similair decks for hours and days to get 30/30/60 gold.
Create unique decks for situations (I’m thinking no more than 5 minutes to craft a deck for a particular scenario, that’s assuming you don’t craft one that can take care of multiple scenarios [Jace is very good for this]) and get 15 Gold per objective. I found it pretty easily to get at least 4-5 objectives done per day, and my time is rather restricted with me taking care of the kids and whatnot.
So, boring grinding for 120 gold per week that takes a lot of time
Or
Creative playing for (at 3 objectives per day) 315 gold per week for little time invested
I would say it’s worth it.
Just a suggestion. If you are playing pvp for gold, then you are going to hit the point where you can’t play because it will put you at 16th or above. Use this time to craft a deck and get objectives out of the way.
Also, suggestions for objectives:
Commander: Hangerback Walker/Any card that summons thoptors. Each thoptor counts as a creature summoned, so summoning hangerback and killing him (Liliana/Chandra?) will be enough to beat the objective
Destory/Sacrifice X creatures: With the current bug, sacrifice actually only counts when an opponents creature is destoryed - Chandra (Burn spells), Liliana (Death spells), Gideon (Guardian of Meletis + 3rd Ability buff and 1st ability buff, followed by supports and 2nd Ability buffs for a near indestructible wall that can’t attack)
Win in X turns: Nissa (only save up for 2nd ability). Can take a lot of tries at chapter 3, but a good starting hand with a near epic first turn cascade or match 5 will get the job done
Cast X spells: Chandra (Burn), Jace (Bounce/Turn to frog/Drain mana)
Survive with x life: Use Gideon and immediately quit the game. He will end up with low life. Start a new game, and cancel all cards until the enemy hits you once to put you under. Then summon your whole hand and use first strike or defenders to beast your way to victory
Take x damage: Orbs of warding or Lifelink. It doesn’t matter how much life you have, only that at some point you took that much damage.
Cast X supports: Jace (control the game with claustrophobia and bounce while waiting for supports), Gideon (starfield of nyx, cheap supports, focus on destroying your own supports to recast them with nyx)
